Does an LSR Moulding Machine Need Auxiliary Equipment?

Introduction to LSR Moulding Machine Setup

Does lsr moulding machine need auxiliary machine?

With the development of liquid silica gel industry in recent years, the demand for liquid silica gel equipment is becoming more and more obvious. So what kind of structure is liquid silicone injection molding machine, it needs auxiliary equipment? And a variety of other molding equipment similar reasoning, the same is the need for auxiliary equipment.

How Liquid Silicone Injection Molding Machine Works?

We first analyze the principle of liquid silicone molding, lsr moulding machine is a liquid silicone material injection molding of advanced tools. Liquid silicone is divided into A/B two-component, need 1:1 dosing, and then evenly mixed and then injected into the hot mold instant curing molding.

Why Auxiliary Equipment Is Needed for LSR Moulding?

In the process of replacing raw materials and products out of the mold need to use a certain air pressure; in the A/B material mixing at the same time, to prevent too fast curing, need to use cooling water; some special products to prevent product trapping, and the way of vacuum; most of the baby class and medical products, the requirements of the low molecular compounds in the material as far as possible volatilization will be the use of the second vulcanization process.

Comprehensive situation, liquid silicone injection molding machine in the use of the process requires the following four kinds of auxiliary equipment.

1. Chiller

Cooling Support for Liquid Silicone Injection Molding Machine

Used for dynamic screw, injection nozzle rubber cooling, as well as oil temperature cooling, cold runner molds also need to use the circulating cooling water. Commonly used chiller has a water tower type or air-cooled, air-cooled cooling effect is more stable than the water tower type, and less waste of water resources, so the choice of air-cooled more. Usually a liquid silicone injection molding machine to choose a 4HP or 5HP air-cooled machine can be.

2. Air Compressor

Essential for Pneumatic Functions

Used for pneumatic pressure plate action, as well as mold running air pressure action, injection nozzle sealing valve needle action. Need 0.8Mpa or so of compressed air, usually with a storage tank form of air compressor.

3. Vacuum Pump

For Specialized Product Requirements

Used for some special products vacuum. Vacuum pump selection and the size of the mold and the situation is related to the pumping rate, pumping value to make the appropriate choice.

4. Oven

Secondary Vulcanization Process in LSR Moulding

Used for secondary vulcanization, in medical products and baby products need to be used in the second vulcanization, according to the performance of the material, 180 ℃ -200 ℃, 2H-4H conditions, mainly in the silicone product of some low molecular compounds to fully evaporate, to ensure that the stability of the molecular structure and performance.

According to the capacity, you can choose the size and the number of layers of the oven is equivalent, commonly used 20 layers of double-door structure. When choosing an oven, you need to pay attention to confirm that the temperature can reach the required requirements.
