Types of Injection Molding Machine(Machine Type)

The injection molding machine(machine type) produced by our company mainly include the following types:

High Speed Injection Molding Machine
Not only high speed/low pressure injection movement and multiple parallel movement the new concept injection machine combined,but also utilized optimized clamping unit and lubrication unit and regenerated hydraulic system,thereby it guarantees a shortened circle time for thin wall products

 

Two Platen Injection Molding Machine
Two-Plate Injection Molding Machine features a European-style pure two-plate clamping structure with non-contact tie-bar design. Its compact body layout further reduces floor space requirements.

 

Servo Injection Molding Machine
Servo Injection Molding Machine is a highly energy-efficient plastic molding machine that uses a servo motor to drive a hydraulic pump.

 

Double Color Injection Molding Machine
Turntable control by servo motor.Injection unit with single cylinder structure and guide linear.Injection unit frame with space can install small unit or short screw.

 

Advantages of Injection Molding Machine(Machine Type)

 
Servo Motor For Injection Molding Machine manufacturers

Design Flexibility
One of the biggest reasons to go with plastic injection molding over other manufacturing processes is how much control you have over the final part. From simple shapes to complex geometries, plastic injection molding allows for a level of detail unmatched in typical molding or machining processes.

 

Enhanced Quality
Plastic injection molded parts are often stronger and perform better than parts produced by other forms of manufacturing. They often last longer than other parts and can hold up better to harsh conditions.

 

Fast Production
With injection molding, the time to mold a plastic part can sometimes take as little as 15-30 seconds. The only thing that takes any notable amount of time in the injection molding process is creating the mold itself. Once that is done, part production can begin right away.

Automated Manufacturing
After you design your mold, the rest of the injection molding process is nearly all automated. A single operator can manage multiple machines at once, with computers and robots handling most of the labor.

 

Cost Efficiency
With the plastic injection molding process largely automated, the need for human operators is minimal. Those reduced labor costs equal a significant cut in the overall cost that it takes to manufacture a part.

 

Waste Reduction
As the world tries to become more environmentally conscious, industrial manufacturing processes are one of the first places to get caught under the spotlight. This is especially true for the plastic industry, which can create a large amount of non-biodegradable solid waste if the plastic isn’t properly recycled.

FAQ

 

Q: How does an injection molding machine work?

A: An injection molding machine works through a cycle of heating, injection, cooling, and ejection. Plastic pellets are melted in a barrel, then injected under high pressure into a mold. After cooling, the mold opens and the finished product is released. This process ensures fast and consistent mass production.

Q: What materials can an injection molding machine process?

A: An injection molding machine can process many thermoplastic materials such as PP, PE, ABS, PET, and PC. Each material offers different properties like strength, flexibility, or transparency. Material selection depends on product application, durability requirements, and cost efficiency.

Q: How to choose an injection molding machine?

A: Choosing an injection molding machine depends on product size, material type, mold design, and production volume. Other factors include energy efficiency, automation level, and precision requirements to ensure stable and cost-effective production.

Q: What is the lifespan of an injection molding machine?

A: A high-quality injection molding machine can last 10–20 years or more with proper maintenance. Regular servicing of hydraulic systems, electrical components, and mechanical parts is important to ensure long-term stable performance.

Q: What maintenance does an injection molding machine need?

A: An injection molding machine requires regular maintenance such as lubrication, oil replacement, cleaning of components, and inspection of electrical and hydraulic systems. Proper maintenance ensures stable operation and reduces unexpected downtime.
