The classification and use of the cold rolled steel and the cold rolled coil

Cold-rolled steel is short for the thin cold-rolled steel which is made from ordinary carbon structural, commonly known as the cold plate. Cold plate is the steel that made up of ordinary carbon structural steel hot-rolled steel belt; the thickness is less than 4mm after further cold rolling. The cold plate has a favorable quality and high precision in size because it is made in the room temperature and would not produce scale, plus with the annealing treatment, the mechanical properties and process performance are better than hot rolled steel, in many fields, especially in home appliance manufacturing areas, has been gradually replace the hot rolled steel.

Applicable grades: Q195 Q215 Q235 Q275 SPCC (Japan brand) ST12 (Germany brand)

Symbol:

1.      Q- The code for the ordinary carbon structural point (limit), it is the first word of Chinese phonetic alphabet. 195 215 235 255 275-represent the number the cold-rolled steel can bear (limit), the unit (MPa ). The Q235 is the best in the strength, plasticity, toughness of the ordinary carbon structural, it can meet the demand of daily use, so the application range is very wide.

2.      S-for steel. P for plate. C for cold-rolled. And the fourth-regular grade C for common.

3.      ST for Steel and the number 12 stand for the ordinary cold-rolled steel.

Mark: size precision-dimensions-plate breed standard

     Cold-rolled steel: Steel-technical condition standard

Mark example: B-0.57501500-GB708-88, Steel, Q/BQB402 Standard, grade (SPCC), annealing heat treatment state plus level(S), table textured D, with central processing status to surface quality level for FB trimming steel; the thickness is 0.5mm, B precision of width 1000mm. a level precision ,length is 2000mm, A level precision ,roughness of PF precision. A, is marked as: steel ECQ/BQB 402-(SPCC)-SD-FB/(A2000A-PF.0.51000A)

Cold-rolled steel: Q225-GB912-89

The main origin: Bao steel, steel, Ben steel, Wu steel, Han steel, Bao steel, Tang steel, Lian steel, Ji steel and so on.

High quality cold-rolled steel: mainly include all kinds of high quality cold-rolled steel; the most commonly used is the carbon structural, especially for deep drawing, which is composed of low carbon cold-rolled steel. According to the surface quality, divided it into three parts: I II III, respectively the special senior, senior and high rough surface, according to the drawing, can be divided into ZF, HF and F, due to the toughness of the steel, can deeply divided into A and B, is widely used in the automobile tractor industry.

Cold-rolled steel: with smoothly surface, excellent in processing, commonly used in the automobile refrigerator washing machine and other home appliance, it is also used in the industrial equipment and all kinds of building material. With the development of economy, the cold-rolled steel is called as the material of modern society.

The classification of cold-rolled product: hot rolled pickling, rolling hard, ordinary cold-rolled, galvanized (galvanized fingerprint resistant, hot dip galvanized), zinc, tin plate, coating, electrical steel (silicon steel ) and so on.

American-style cabinet, soft close hinge demand to follow the trend

American-style cabinet, soft close hinge demand to follow the trend

By Kingwen Liang

Damping, the pursuit of high-end household, about the application of damping, Kingwen Liang has been mentioned in the previous article.

And recently, more and more customers made an inquiry about soft close hinge, the quantity that customer need is also growing rapidly.

Originally, the U.S. market has always been the top priority of China's furniture exports. However, due to different tastes of American customers, the short arm hinge has a majority used in the U.S market in order to maintain the high-end of American furniture. American furniture and cabinet factory are fond of Blum hinges, hettich hinges and other international brands, while the domestic cabient hinges are rarely used.

But in recent years, more and more manufacturers which produce American-style cabinet have emerged in mainland of China; the domestic manufacturers have a better understanding of hinge that made in China, knowing that it is getting better and better, thus make the manufacturers trend to choose domestic hinge in order to save time and cost and maintain the quality at the same time.

While the hinge hydraulic system appears, attract a large number of American-style cabinet manufacturers.

Since last year, there have been dozens of American-style cabinet manufacturers, both at home and abroad came to Long Sheng hinge factory in person, or call to inquire whether the American hinge damping effect can be integrated.

Now, in order to meet the market demand, has developed an integrated damping kitchen hinge, hoping to really fill a gap in the market. (Such as the opening title picture above)

The key factor affecting the lifetime of cabinets

The key factor affecting the lifetime of cabinets

Coupling head is also called door hinge .It is the key component connecting cabinet and cabinet doors . Hinges stand the most test in our usual cabinet usage .So it is pretty important to choose hinges with excellent quality .The common opening angle of cabinet hinges is 90 and 95 degree which turns to be a right angle when the door is opened .There are also special angle hinges ,such as 165 degree hinges which the opening angle is 165 degree which the door can be more open and easier to reach things in the cabinet .Normally ,hinges are divided into one way and two way .One ways hinge can meet normal usage ,but two way hinges are much better . We also mentioned the difference between one way hinge and two way hinges in our article . Most hinges in the market are removable and are consisted of mounting plate and hinge body .We need remove hinge body together with cabinet doors and check the inner side of hinge .So irremovable hinges are not convenient in installment ,but same usage .

The steel of making hinges is very important . If you cannt choose it well , the door may stagger forward and back, and off angle .Cold rolled steel is popular in many famous top grade hardware factory ,cause its thickness and toughness are perfect .but there are also many manufactures use stainless steel material .Cause it can remedy the weakness of rusty in wet area when using normal steel . The thickness of steel is also a important element affecting hinge quality ,which decides how many load capacity can the door hold . So we must pay attention to this when selecting cabinets .

In addition ,you should try to choose damping hinge. The so called damping hinges means it will last a certain angle when the door is closed to avoid the door impact and noise caused by the hinges ,so your cabinet will not suddenly turn off ,thereby ensuring the usage of security .Besides damping hinges ,there are also rebound hinges .When people hands full of things ,then it is the protagonist. People only need to touch the cabinet door gently with body ,and it can open automatically ,which make our daily life more convenient .

Finally , the hinge must be able to adapt to the wet ,smoke and many other factors in kitchen .Cause it plays an important role in the lifetime of cabinets and takes the most tests ,not only linking the cabinet body and doors together ,but also bear alone the weight of the door and maintain consistency door arrangement unchanged , after a certain period of time, it will be loose .In the whole drawer design ,the most important accessories are drawer slides. Low-quality rails maybe be good in the short term ,but you will find it difficult to pull and push when it is used for a long time .The phenomenon is suitable for any products ,especially for big products .

Thus , "If the furniture hinge is the heart of the cupboard, then the rail is the drawer kidney” .This saying is without any exaggeration and customer must pay attention to the furniture hardware accessories when purchasing cabinets .

Okuma (16 mm)

Hinge Installation Tips:

1. Minimum clearance

Minimum gap that opens the door when the door side of the minimum distance required. Minimum clearance distance from C, and the hinge type door thickness determined. When the door is rounded, the minimum clearance reduced accordingly. Minimum clearance required from each different hinge correspondence table lookup.

When the two share a side door when the total required clearance should be twice the minimum gap so that both doors can be opened simultaneously.

3. C distance

C refers to the door and the hinge cup from the edge of the distance between the holes. Each hinge maximum available C size due to different hinge models and different. C The greater the distance, the smaller the minimum clearance.

4. Door covering a distance

Refers to the distance covered door side door covering the distance.

5. Gap

Means the entire gap with the cover, the door from the outside edge of the cabinet; the half with the cover, the distance between the two doors; including the case of the side door, the door edge gap refers to the inner edge side cabinet distance.

6. Each door hinge required number

Width of the door, the door height and material quality door hinge of each door number required determinants. In practice, various factors appear as different circumstances and different. So the figure above the number specified in the hinge only as a reference. In cases is unknown, it is recommended to do a test. For the viewpoint of stability, the distance between the hinge should be as large a number.

X = the distance between the hinge (this figure, when a 19 mm thick particle board, weight 750 kg per cubic meter of hinge used when the number)

Patent case arms of Yubo two private parties to join hands break overseas markets

(Reporter Dong Xiaojun correspondent Shu Qin Xie Ying) with a patent infringement lawsuit, the judge under proper mediation, involving not only the two private enterprises to give up a fierce fight, and turn hostility into friendship and cooperation, jointly cope with international competition.

TUNG very sure that the Australian state company for foreign production of these products, related to their "three-dimensional adjustable  hinge" patent. Australian state companies believe they are based on orders placed by foreign production, does not constitute infringement, but also in the TUNG prosecution, they have National Patent Reexamination Board made a request to declare, "three-dimensional adjustable door hinge" patent invalid .

Judge handling the case told the original defendant, if the two sides continue to opposition proceedings will face extremely complex process, but the plaintiff's patent once it has been determined to be invalid state authorities and foreign can take the opportunity to keep the prices down, Ningbo enterprises will therefore be completely lost in such products international pricing initiative.

Can we distinguish high quality hydraulic soft close hinge from the one with bad quality via intuition？

Yesterday, I met a boss whom I’ve known him since 2001 and we’ve done business for four or five years.
He was so happy to meet me at the gate of his factory as soon as I got off the car. “Glad to see you again,Kingwen”, He said.
“Yeah, long time no see”, I answered him with a smile. After 2006, we have not seen each other nearly for 6 years, due to the fact that clients demanded much higher level products，so that they changed hinge supplier.
After greetings and knowing recent situation between us, he showed me our kav brand soft close hinge and said “The soft close function is a little fast. It seems that the hinges we use now are better. Is the buffering effect not enough? It is better that the door can soft close at angle of 30 degree and will not produce noise.
“It does not matter, and we can adjust its speed as long as you put forward your demands. I am here now, and we can solve all problems right away. Or if you have any new requirements, extra function or new design, maybe I can help you out.  Also you can ask a technologist to install this soft close hinge with me and compare it with your previous ones and which one is better can be found out soon” I said. They readily agreed, after finishing installation, he looked at it and said the effect is almost the same.
Moreover, when he pulled the door at 35°Angle and then loosened his hands, the soft close hinge they used before didn’t have the function of buffering and made a big noise, while our kav brand soft close hinge soft closed with great buffering function and without any noise.
Now customer is very satisfied with our soft closing hinge, and he knew some of his friends also have been using our concealed hinges for years. He suggested that he will place order for our soft close hydraulic hinge and soft close slide in a few days.

So, here underline again by Kingwen, I already uploaded lots of articles about how to distinguish hinges. Currently, with the increasing requirement of customers and development of domestic soft close hinges technology, it is difficult to distinguish soft close hinge of bad quality from the one with good quality, if only with our eyes and several close-open movement. We have to try to use them and as the time goes by， there will show up the differences.

What do you think?

The metal cabinet brand selection

To introduce the following Cabinet Hardware in hinges and drawer choice:

First, the concealed hinge

In peacetime cabinet doors frequently switch process, the most important thing is probably tested the hinge. Not only does it accurately to the cabinet and door link up, but also to bear alone the weight of the door, and cabinet doors switching times of tens of thousands, but also must maintain the consistency of the same gate array, or after a period of time may laughter. If there is no one "reinforced steel frame" and perfectly pliable performance, it is difficult to undertake this task. Currently hinge cards generally have two bits and three card-bit, and can basically meet the use, of course, three cards hinge bit better. Seen on the market today are mostly removable hinges, base and snaps into two parts, in the selection of cabinets may require sales staff together with the door hinge snaps are removed together, take a look inside snaps. And the production of steel hinge is the most important, like the election is not good, after some time, the door may laughter, slipped off the shoulder angle. Cabinet hardware brands almost all use cold rolled steel, its thickness and toughness are perfect.

Second, the basket

Kitchen items are our most frequent daily contact, kitchen utensils is also the largest variety of everyday life, and out of the kitchen and ultimately, three meals a day, but inevitably moving and hauling pots and pans.

Why is there such a wide difference among price of Chinese cabinet hinge?(original)

By Kingwen Liang

 “Why is there such a wide difference among price of Chinese cabinet hinge? ” Many customers discuss this subject with Kingwen Liang.

There are thousands of Chinese cabinet hinge factories, 99.9% of which are located in Guangdong.

Guangdong has become the center of spring door hinge production. It can be divided into several main centers according to location. Kingwen Liang will introduce this subject in following articles.

Many hinge buyers will not know what to do after inquiring the price of concealed hinges on line or in fairs.

For example, there are two normal two-way hinges, whose appearance and weight are similar, but the price is from 0.7 RMB to 1.5 RMB per piece. The highest price is two times as the lowest price. The layman can’t tell the difference among quality and price according to appearance and weight of hinge.

On this point, if a hinge buyer need to purchase large quantity of hinge and require high quality, maybe he should go to the hinge factory to have some acquaintance with the productive technology, QMS and production scale of hinge manufacturer.

First, productive technology of hinge

For instance, some hinge factories adopt fully automatic production equipment to produce the whole hinge, including hinge plate, hinge arm, fastenings and so on, so the quality of hinges produced by these factories will have guaranty. If the factories adopt the fully automatic equipment to produce hinge with one-step molding technology, one set of the fully automatic mold cost almost 200,000RMB, which demands the factory have a certain scale, or it can’t bear the cost of the expensive mold and reserve of talents. The quality control standards of these factories are strict and won’t allow the defective products to escape into the market. However, it’s ok for some other hinge factories to just stamp the look of hinge, assembly them and won’t inspect the quality. Then regard them as finished product and put them into market. This is one of the reasons of why there is such a wide difference among price of Chinese furniture hinge.

Second, material of hinge

For hinges produced with fully automatic production equipment, they are made of brand new material and there is a sign of cut, which the expert can discover just at a glance. But some hinge factories use leftover material to produce hinge. Some of them just roll the oil drum and then use them to make hinge, some of them use SECC and so on. Factories adopting fully automatic equipment use brand new material to produce hinge, while some factories use leftover material to produce hinge. If a hinge is made of leftover material, the thickness of one hinge is different or what is more, there is mixed material in one hinge, including cold rolled steel, galvanized sheet, oil drum material, etc. so their price will be much cheaper. This is the second reason why there is such a wide difference among price of Chinese furniture hinge.

Third, finish treatment of hinge

There is a big difference among price of finish treatment of hinge. Normally, a better finish treatment is first copper plated and then nickel plated, but the merits or defects of an electroplate factory also need to be considered. Though some electroplate factories apply this plated process as well, they use second-hand material to electroplate, which result in the electroplating effect is even worse than electroplate with nickel directly. New hinges made by some inferior hinge factories will rust before unpacking.

Fourth, quality of hinge accessories

Heat treatment of hinge accessories, such as U-shaped screw, screws and so on, is one of the important factors to affect the quality of hinges. Customers can’t tell whether the hinges have heat treatment or not with eyes, but whether a hinge can pass 50,000 close&open test or not is according to heat treatment. The fact is that the close&open test of lowest price hinges will appear these or those problems within 8,000 times, which is another reason why there is such a wide difference among price of Chinese furniture hinge. However, newly-built hinge factories hardly can reach the best effect of heat treatment.

For thorough analysis towards the problem of wide difference among price of hinges, hinge buyers should choose suppliers according to their quality requirement.
