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.

2.Silicon rubber for mold making features
Silicon rubber for mold making is white or red flowing liquid with general hardness of 22-50Aípafter curing. Molding silicon rubber is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength ,tear strength and elongation.
3.Silicon rubber for mold making operations
If the customer wants to make large products and large size molds, the mold should be made of silicon rubber with high hardness. On the contrary, if the mold with fine and precision patterns, it should be made of silicon with low hardness. The amount of the curing agent depends on the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.
The manual molding silicon is mainly applicable to manual molds and small number of product duplication with all kinds of samples and the curing agent is free.
2. The manual molding silicon application:
The manual molding silicon rubber is mainly applicable to manual mold design, pvc plastic molds, cement product molds, melting point alloy molds, alloy toy craftworks, plastic toy craftworks, gifts and stationery, large statues, duplication of cultural relics, shoe sole mold fabrication, pad printing positioning, shock resistance for electronic equipments, etc.
3. The manual molding silicon instruction:
1. The manual molding silicon is applied to small products or products with fine patterns. The mold for the fine detailed and small products should be made of soft silicon to protect the products from easy breaking when demoulding.
2. If large product duplication or fabrication, the mold should be made of higher hardness silicone rubber so that the products made will not deform.
