We closely keep up with the latest techniques and monitor the newest trends and development of the mold manufacturing. The successful application of the gas-assisted technology in mold area is one of our achievements. These techniques in mold have become more and more popular for the below advantages:
1.Saving material.
2.Shortening the turnaround time.
3.Decreasing the injection pressure and prolongs the lifetime of the injection machine.
4.Decreasing the cavity pressure and the lock force of the mold and then increase the working life ííof the mold.
5.Easy to improve the surface defect of the product.
Because there are so many benefit from gas-assisted mold and its prosperous potential, we have conducted many research on it. Now we gain enough experience on it design, manufacturing and application and build up a group of experienced engineering staff that focused on it. Besides, we continuously aim at the latest achievement in this filed, and invite the expert to our company for training. We keep good business relation with the famous facility supplier in world. We believe we can provide you the excellent service of gas-assistant mold basing on our professional experience and spirit.

Precise mold take a big volume of the mold manufacturing industry, and the percentage will continuously increase. We notice the trend in this industry and greatly enhance the design and manufacture capability on the precise mold. The precise mold is different with the traditional mold. Because the shape and construction are complicated and the manufacture level is much higher too, so it is difficult to apply the traditional manufacture methods on it. Only the advanced manufacture technology can succeed in it.
íí in order to meet such precise manufacture requirement, we have purchased many high precise requirements and provide the solid foundation for the precise components manufacturing. We not only invest in the hardware, but also the engineering staff. We provide many related trainings to them and introduce them the different design concept, and apply the concept in the practice. Such efforts reinforce out advantage at this area. The precise mold has corresponding high percentage of our business. The production lines include office-automatic product and mobile phones, etc. Basing on the advantage of the equipment, techniques and experience, we can provide you the satisfied service with a high quality aforce out advantage at this area.

We have accumulated a lot of experience in hot runner system mold. Our designer and engineer are familiar with dme, hasco, yudo, mold master, mastertip, husky hot runner system. Many factors have to be taken into consideration for the hot runner system, for example: the shape, size and thickness of the part; the layout, the gating location, also the property of resin and so on. With the help from hot runner supplier, we will select the best-fitted one for you. Furthermore, we could provide you favorable after-sale service.
Hot runner mold theory:
ííwith heat manifold and heat drops inserted in injection mold, the resin could keep in the molten state as it flows through the barrel. Then it gate into the cavity just as inject directly from the machine nozzle. No runner and cold sprue will exist during the production.
Hot runner benefits:
1. Reduce cycle time a lot and then increase the production efficiency.
2. Improve the gating appearance.
3. Little waste or no waste of the resin.
4. The hot runner could reduce the flow resistance and then the injection pressure and clamp force could reduce a lot. Then it offer opportunity to produce the flow strained part.
5. Fewer mold-in stress.
