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.
Runner Design Injection Molding System Design
The gate is the connecting part between the runner and the cavity, and is also the end part of the injection predeformation mold gating system, the molten plastic enters the cavity and core side through the gate directly. The function of the gate is make the molten plastic coming from the runner enter and fill the cavity with core by fast speed, after the cavity with core are filled with plastic, the gate can be cooled quickly and sealed to prevent the hot material in the cavity from flowing material.
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.
What Is The Side Parting And Core Pulling Mechanisms With Their Function?
When there are holes, cavities or cores on the inside or outside of the injection-molded plastic parts that are different from the opening and closing directions of the mold, the plastic parts cannot be directly pushed out of the mold by a push mechanism such as a ejector pin. So we will make the movable parts that can move laterally, and then before the plastic parts are demolded and pushed out, the laterally formed parts can be pulled out first, and the plastic parts can be pushed out of the mold, otherwise it cannot be demolded. The entire mechanism that drives the laterally formed parts for lateral splitting and core-pulling and reset is called the lateral splitting and core-pulling mechanism. For the case of forming lateral bosses, it is often called side parting; for forming side holes or undercuts, it is often called side core pulling.

USM is one of the world's leading manufacturers of plastic injection mould and molded parts, medical molding & manufacturing. We have always pushed developments forward and set benchmarks in Automotive, High precision, and 2K molding, and other industrial parts.
Screw vacuum pump is a kind of equipment that uses a bunch of screws to produce suction at high speed to achieve exhaust effect, which can effectively eliminate water vapor and dust, and has important applications in medicine, chemical industry and other fields.
Plastic Mold Parts Manufacturing
USM is a one-stop service for plastic precision mold and injection moulding manufacturers in China, as we know, perfect molds are related to professional mold design, high precision processing machines, rich experiences assembling workers, and team management.
There are 7 sets of high-speed MAKINO V33I CNC machines which bought from Japan, and SODICK EDM machine and wiring machine in USM, the mold parts tolerance can be made in ±0.005mm, it is the key point to make the parting line perfectly, and also it can be assembled directly after processing finishing.
