How Does The Die-Casting Mold Improve The Damage Caused By Stress? Stresses include thermal stresses and mechanical stresses, mainly due to mechanical, chemical, and operational shocks. Heat is specifically produced in the following ways. 1. In the process of die casting production (1) The cooling temperature control system should be set to keep the working…
How To Improve The Flexibility Of Plastics? Intuitively, the flexibility of plastic refers to the softness of plastic products, that is, the softer the plastic products, the better the flexibility. In polymer physics, flexibility is defined as the property of a polymer chain to change its uniformity. The flexibility of a plastic depends on the…
How To Reduce The Density Of Plastics? Reducing the density of plastics means that the relative density of the plastics is reduced by appropriate means to suit the needs of different applications. The methods for reducing the density of plastics include foaming modification, adding lightweight fillers, and blending lightweight resins. 1. Foaming modification Foam molding…
Six Development Directions Of Mold Design 1. Material selection The greenness of the mold material has a very important impact on the green performance of the final product. The choice of materials for green design must be based on green materials, abandoning the chemical methods used to surface the materials in the past, and replacing…
Factors Affecting The Stability Of The Mold And Stamping How to improve the stability of the mold has become a realistic problem faced by mold manufacturing enterprises. Designer experience and skills play a key role in the design and manufacture of molds. Whether the design is reasonable or not can be confirmed by trial mode.…
Abnormal Wire Cutting Processing And Analysis Slow wire cutting has an indispensable position in the manufacture of precision molds, especially in the manufacture of stamping dies. The punching die, the punch fixing plate, the die and the unloading plate and the like all require a slow wire cutting process. Processing quality and efficiency directly affect…
How To Increase The Density Of Plastics? Increasing the density of plastics is one way to increase the relative density of the original resin, mainly by adding heavy fillers and blending heavy resins. 1. Add heavy filler. Includes the following: (1) metal powder; (2) Heavy mineral fillers. 2. Blending heavy resin This method is relatively…
Basic Work Cognition Of Injection Molding Machine 1.Melt temperature The nozzle can be measured or measured by air jet. When using the latter for measurements, care must be taken to ensure that hot melt plastics are cleaned without accidents, as hot melt plastics can burn the skin and even corrode the skin. In the injection…
How To Disassemble The Screw Nozzle Of The Injection Molding Machine? The plasticizing device is generally provided with an integral rotating mechanism. When loading and unloading the screw nozzle, screw and barrel of the injection molding machine, firstly, the injection molding positioning screw should be loosened to deflect it from the original position by a…
Repair And Maintenance Of Screw Nozzle Of Injection Molding Machine If there is a one-side contact or poor contact in the contact part between the nozzle and the mold positioning sleeve, the front end spherical portion R will be deformed to form a groove in which the melt escapes, causing the nozzle to overflow, and…
