What conditions should injection molding have?
Injection molding is a wide range of knowledge, technical and practical industry. In the process of injection molding production, plastic raw materials, color powder, mouth material, mold, injection molding machine, peripheral equipment, fixture, spray, all kinds of auxiliary materials and packaging materials, etc., which bring a lot of workload and certain difficulty to the management of injection workshop. So, what conditions should injection molding have? Let's look at it briefly.
- Different materials, the temperature required for injection molding is also different. For example, if the temperature is too low, the color of the liquid material will attack some abnormal situation; Assume that when the temperature is too high, the product will have a rough appearance in the future, and the production quality cannot meet the demand.
2, when the injection molding needs to be careful to control the speed of the pouring channel, assuming that too fast when there will be raw edge, but also cause the filling and burning situation. Assume too slow when there will be shrinkage appearances, as well as a brief cracking and so on. So when pouring must be careful to control its processing speed, so that the quality of the products produced to reach the requirements.
3, in the processing of the need to be careful to control the cooling time, the detailed demand of the time also needs to choose according to the details of the processed products. The processing of injection mold will have a greater impact on the brightness of the finished product, so it is necessary to pay more attention.

Points for attention in injection molding design
2014-09-03Prepare for the design phase, plastic injection molding process here should first determine what kind of injection parts to do. At the beginning of accepting the design task, if the customer has a simple design drawing, it should be adapted according to the customer's simple drawing and made into the regular parts drawing, repeated communication with the customer to determine the drawing. At the same time indicate the specification and technical requirements, production yield, sample shape scale, surface roughness, volume and quality. Review cases, collect relevant information, sort out injection molding design data, molding process, molding equipment, mechanical processing and special processing data, ready for use.
Application of two - color injection molding technology in the manufacture of household appliance mold
2022-09-01Two-color injection molding is a technology that can produce a high surface gloss and two different colors inside and outside the plastic parts in one molding. The application of this technology can greatly improve the appearance of the whole machine product. Compared with the ordinary mold and the small two-color/two-component injection molding that has been widely used at present, the large two-color injection molding mold has great differences in product characteristics, mold structure, action sequence, gate setting, flow channel layout and other aspects, and the difficulty is greatly increased.
