Cold forming and cold heading all refer to the same process in which a metal is shaped in closed die by means of pressure. Thereafter, the metal then deforms at room temperature. No metal cutting or heat is involved.
China Turned Parts has solidified its place as the most reliable and experienced manufacturer of cold formed fasteners and other turned components. Their cold forming technology is pretty much advanced and so the company takes pride in offering superior quality high volume parts.
Cold forming stands out from other processes such as casting, turning, machining and hot forging in many ways. For instance, in hot forging, the material is usually heated before being formed while in casting the metal is melted and then solidified.
Well, the unique attributes that cold forming has also double up as the benefits it possesses over all the other processes we’ve mentioned.
They include:
Little wastage of raw materials
As we mentioned earlier, the process only utilizes pressure to shape the metal.
A piece of wire is usually held in place and when there’s an impact on the end of it, it causes the material to ‘mushroom’ thus creating a great head for a fastener without slicing off any piece of metal. After the head is formed, the threads are either rolled or cut.
So unlike machining, no material will be cut off and this helps to reduce wastage of raw material.
High output
Cold heading is known to generate, at the minimum, one part per second. In a minute, the process could generate tens to hundreds of parts rapidly. This makes the process incredibly faster and efficient than any of the other alternative processes.
In fact, cold forming is the perfect alternative in the case where there’s a huge demand for small machined parts. And since a cold-formed part is able to perfectly replace a multiple-part assembly, one is assured of huge savings and significant economic gains.
Powerful components
For the material to have superior hardness and strength, the material grain must be reformed to make it flow into the desired shape which is exactly what cold forming does.
Great finishing
You won’t be needing to do any further finishing on components that undergo cold forming because the resulting surface is usually so smooth and fine. So in the case of formed fasteners, you can use them right away without worrying about their texture or appearance.
Consistency/Close tolerances
One of cold forming’s greatest attribute is consistency. And thanks to this, there will be very little secondary processes as well almost none non-conforming products.
Integration of components
Cold heading lets independent parts to be joined together into one component there by enhancing strength and making the whole process cost efficient.
Friendly prices
Putting in mind that there’s very little wastage of materials, high output, and the process itself is cost efficient, this simply means that the price of components such as formed fasteners is going to be pretty much affordable.
Cold Forming Materials
Here’s something worth mentioning: the best material you would use to cold form a part is not going to be the best material you would also use to machine it. This is part of the reason why you should only work with an experienced Fastener Company.
Two of the most vital factors that should be considered include ductility and material flow. Also, the presence of elements such as sulphur could as well affect the cold forming process. Another important factor is the yield to tensile strength ratio.
At China Turned Parts Limited, they will work with you to find out the proper alloy for your specific parts when they are cold formed. Better still, Pattern Fastener’s cold forming technology has evolved from its simplicity to a more complex technology that can generate hundreds of superior quality formed fasteners and other parts efficiently and more economically.
