paring with water-assisted injection molding technology and gas assisted injection mol ding technology, the fundamental difference is the nature of the auxiliary molding media used. One is liquid and the other is gaseous nitrogen, water is incompressible but gas does. The viscosity of water is higher than gas, and the thermal conductivity of water is 40 times than gas, the heat capacity is 4 times than gas. Although the theory of water-assisted and gas-assisted injection molding are the same, most technicians believe that water assisted injection moulding will not replace gas-assisted injectin molding, it depends on the application and mold.

Since the thermal conductivity and heat capacity of water are much bigger than nitrogen, so the injection cycle of water-assisted is about 70% shorter than the injection cycle of gas-assisted molding; The product wall thickness of water-assisted injection molding is more even than gas-assisted; The inner wall roughness of water-assisted injection molding is smoother than that gas-assisted injection molding.

TV Frame Mold USM team has over 16 years of rich experience in gas-assisted mold manufacturing and mold trial, which can satisfy the mold making and injection of common gas-assisted products in the market, always serve the customer with high standard, high quality, fast delivery time, and competitive price. Advantages of Molding Around TV 1. The shrinkage mark is very small and can be removed; 2. Lower injection pressure of this gas assisted injection moulding can make the part stress smaller; 3. Lower stress and deformation can make higher product stability. As one of injection moulding manufacturers, we will do our best to meet all the needs of customers.

A china dry screw vacuum pump is a device that generates, improves and maintains vacuum in a closed space by various methods. A vacuum pump can be defined as a device or device that uses mechanical, physical, chemical or physicochemical methods to extract gas from a vessel to obtain a vacuum. With the development of vacuum applications, many kinds of vacuum pumps have been developed, and their pumping speed has ranged from a few tenths of a liter per second to hundreds of thousands and millions of liters per second. The ultimate pressure (ultimate vacuum) ranges from coarse vacuum to extremely high vacuum above 10-12Pa.
