Our classic case

THREEUP's porous steel have been approved by SILVER BASIS

Porous steel is a new kind of Mould Accessories. It is a new kind of porous metal material, which has the advantages of high strength, high toughness, corrosion resistance and air permeability.
The use of the mold can quickly remove the air and plastic volatile gas in the mold cavity, eliminate the defects caused by poor exhaust, such as: scorching, flow marks, lack of material, flaps, etc.

Recently, our Porous steel has been recognized by SILVER BASIS Company and has been successfully used in the latest mold of SILVER BASIS Company and achieved good results, which has been praised by them.


The reverse use of cooling tube is successfully developed in Midea company

The cooling tube is often used in the cooling system of the mold. Its structure is copper shell, copper wall is capillary core, internal heat conduction materials, heat conduction efficiency is 200 times that of ordinary copper. It is very suitable for some mold core products that are not easy to design water to cool down, and heat dissipation through its high efficiency of heat conduction.

But in thermoplastic products, the product does not need to be cooled to form, but needs to be heated to allow the thermoplastic to solidify. When midea company designs a motor mold, the effect of using copper to heat is not ideal. We hope that we can provide a special heat conduction tube to shorten the molding time of the product. After many experiments, our modified heat conduction tube was successfully adopted by the American company, which shortened the production time from 55 seconds to 40 seconds, greatly improving the production efficiency.

Non-standard Ejector Pin is well received by many customers

We have a fully automatic Ejector pin production line, which can produce ejector pin of various specifications, including DME standard, MISUMI standard, HASCO standard such as, we can stock a large number of goods.
However, more and more customers need to use some non-standard Ejector pins in the process of use. Sometimes they are flat Ejector Pins, sometimes they are stepped ejector Pins, and more often they need to process various shapes in the front segment of the thimble, which are suitable for different molds. The past they need to buy back to standard ejector pin and then to processing, so need to waste more time and cost, Now we can customize processing for customers, according to the customer’s drawings, complete processing, so that when customers buy back can be directly installed and used, greatly saving the time of mold development.
