Injection Mold

• The air trapping position in cavity and exhaust method The air trapping in cavity is usually in the following places:1. Thin-wall structure cavity, the end of melt flow;2. The junction of two or more melts;3. The last area where the melt in the cavity rea... More+
• Design standard of exhaust slot The exhaust system should ensure that the gas in the cavity is smoothly discharged, and also prevent the material from entering and exhausting channels from causing flashing of the product or blockage... More+
• Parting surface venting of runner system There are a large amount of gas in the main and sub channel, these gas are discharged through the pull rod (push rod) during injection processing, a part of gas come out from exhaust slot on parting s... More+
• Insert pin of vengting design for molded parts Insert pin of venting:It is difficult to make exhaust slot when end runner is not in parting surface during injection, and there is no matching gap available, but we could make the venting pin at end ... More+

• Five Major Steps of the Injection Mold Production Process Injection mold manufacturing can be roughly divided into the following steps:Process analysis of plastic products. More+
• What is Plastic Injection Mold? The plastic mold is used for injection molding, it is assembled with cavity, core and side slider together, with ejection system and adjustments to produce plastic products by different shapes and sizes. More+
• Design principles for wall thickness of plastic products The principles of wall thickness design for plastic parts are as follows:1. Making the wall thickness even is the first principle of plastic part design, it can make filling, cooling and shrinking eve... More+
• Plastic part ribs desigining The ribs function: The role of ribs is to improve the strength and rigidity of the plastic parts, prevent the plastic parts from being distorted and deformed, and will not cause the appearance of t... More+
• Plastic injection mold runner system design points When designing the gating system, Firstly, we should consider making the plastic melt fill the cavity with core side quickly to reduce pressure and heat loss; secondly, it should be economically cons... More+
• The main design points of the design of the plastic mold pouring system The main runner is the part where the molten plastic first passes when it is sprayed from the injection nozzle, and it is coaxial with the injection nozzle, because of repeated contact and collision w... More+
• Key points of plastic injection mold runner system The sub-runner is a transitional channel between the main runner and the gate, as the sub-runner is the longgest part of gating system, so it is very important to enhance the parts quality and improve... More+
