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.

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.

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.

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.

For medical plastic components manufacturer, it means that medical supervisors are required to supervise and manage the materials used to manufacture the equipment, the medical injection mold parts are designed to withstand high temperatures and chemical corrosion. In this way, it can handle frequent sterilization cycles and any other medical or bodily fluids that come into contact with it.

USM molds focus on structural parts injection molds, gas-assisted water-assisted molds, small parts plastic molds, precision plastic molds, and plastic parts product molds, from mold design to mold manufacturing, mold assembly test molds, product injection molding processing, and the entire process. Service, the precision of the mold is 0.005mm, and the precision of the injection product is 0.02mm. If you have any ideas about molds and products, please do not hesitate to contact us directly.

The same type of material of different colors is usually used for two-color injection molding（or 2k injection molding）so that the bonding strength of the first color and the second color plastic is the best, but due to the functional requirements of the product, the performance difference of the two materials actually used may be very big, if the elastomer is injected into the surface of a rigid material, the most difficult thing to solve during 2k moulding process is the delamination and shedding of the bonding surface of the two materials.

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.

The combination of easy plasticity and elasticity of plastic and rigidity, strength and heat resistance of metal can be firmly made into a complex and exquisite metal-plastic integrated product, it can also reduce product size and weight; The combination of plastic insulation and metal conductivity can meet the basic functions of electrical products, it can also meet some special requirements, such as magnetic permeability, wear-resistance and tightness.

Generally, the temperature-sensitive wire is composed of steel wire insulated with a heat-sensitive material, the temperature sensing wire is commonly known as the "thermocouple", and there are many types, but hot runner thermocouple has two types: standard type J and type K.

Nowadays, gas-assisted injection molding has been successfully applied to the fields of the automotive, home appliance, furniture, daily necessities, office supplies, and other fields, the main products are automotive doors, bumpers, window guides, door handles, large-screen TV shells, and integral tables, chairs, etc., enable many plastic parts that cannot be molded by normal plastic injection molding methods or are difficult to be molded, opening up a new way for plastic parts molding.
