What is a High-speed Injection Molding Machine

What is a High-speed Injection Molding Machine

Generally speaking, the injection speed of an injection molding machine is above 300/s, so such an injection molding machine can be called a high-speed injection molding machine. There are two types of high-speed injection molding machines, one is hydraulic and the other is all-electric. High-speed injection molding machine is a molding equipment specially used to produce thin-walled products. It makes many different kinds of thin wall plastic products, like food container, plastic cups...etc.


What Product Uses the High-speed Injection Molding Machine?

High-speed injection molding machines are currently widely used in the automotive industry, home appliance industry, 3C industry, packaging industry and environmental protection industry and so on.


What is the Difference Between High Speed Injection Molding Machine and Ordinary Injection Molding Machine?

The Difference Between High Speed and Ordinary Injection Molding Machine

The molding process of an ordinary injection molding machine is mold clamping-injection-cooling-material storage-mould opening-mould support-gap time.

The high-speed injection molding machine adopts three-axis linkage, which is generally called a three-circuit. The molding process is mold clamping-injection-cooling-mould opening (synchronous mold support, storage)-gap time. For example, the molding time of an ordinary injection molding machine for a product is 10 seconds, while the high-speed injection molding machine uses the principle of three-axis linkage to greatly shorten the molding time by about 6 seconds. Subtracting two small steps, the time is increased by about half.

The standard pumps used in ordinary injection molding machines have greater pollution in terms of electricity, hydraulic oil and noise. The high-speed injection molding machine adopts a hybrid type of oil pump and servo motor, which is very environmentally friendly.


Reasons for Choosing High Speed Injection Molding Machine

The shooting speed is fast, the ordinary injection molding machine is 100mm/s, and the high speed is generally above 300mm/s. increase work productivity.

Energy-saving, equipped with a high-response servo system, providing corresponding hydraulic oil output flow according to action needs, no overflow loss, saving energy by 30-70%. Reduce operating costs for customers.

Precise, equipped with high-end computer controller, precise position and temperature control setting, faster response.

High efficiency, the new optimized design of the clamping mechanism, the movement of the clamping mechanism is fast and stable, 10%-20% faster than the previous models. Optional servo motor feeding, shorten the molding time by 40% compared with the traditional machine (can realize feeding and opening The three axes of the mold and the supporting mold move simultaneously).

Safety, thickened structure, triple protection of machinery, hydraulic pressure and electrical appliances. The safety module independently controls mold closing, injection, feeding, and seating without any misoperation and human injury.

In summary, high-speed injection molding machines: implement soft-start molds, which will not affect the power network and avoid voltage and electrical radiation pollution. It can effectively prevent the oil temperature from being too high and cool down well. Greatly reduce the replacement rate of hydraulic oil.

Compared with ordinary injection molding machines, high-speed injection molding machines can save 60~70% of the total power, greatly reducing costs and saving resources for customers.


Which Brand of High-speed Injection Molding Machine is Better?

How Much Does a High-speed Injection Molding Machine Cost?

What is the price of a high-speed injection molding machine? This is a question that many buyers will ask. Once you have the idea of buying an injection molding machine, you may want to know how to get the lowest price.

According to different specifications, clamping force, tonnage, system, motor, injection speed, and other configuration options. The price of high-speed injection molding machines will change accordingly. The price of a general high-speed injection molding machine is 50% more expensive than the ordinary injection molding machine. Usually, the price of a high-speed injection molding machine ranges from 10,000 to 100,000 US dollars. But from a long-term perspective, the profit return brought by high-speed injection molding machines is sufficient to make up for the cost gap.
