Introduction of Injection Molding Services
The Plastic injection mold machining is a manufacturing process that requires an injection molding machine, raw plastic resin, injection mold tools.

The precision plastic injection molding process consists of the following key steps.
Step 1: The plastic resin begins as raw plastic pellets. These have been treated by drying, and then if necessary dyeing with pigments or master batch colorants.

Step 2: The pallets is fed into the machine through a funnel-shaped hopper. A reciprocating screw inside the barrel of the machine will inject these resins into the mold’s runner system.

Step 3: Resin pallets are loaded into a heated and compressed chamber called the barrel where they will be melted, forming the liquid resin.

Step 4: The melted resin enters into the mold cavity through a nozzle under high pressure.

Step 5: After the mold’s cooling and solidification, the part has been demoulded to the shape of the mold cavity.

Step 6: The mold halves (cavity or “A” side and core or “B” side) open up and a cycle begins again for the next part.

Advantages of Plastic Injection Molding
Good Finishes
Precision Injection Molding delivers superior appearance, quality, and surface finish when compared with many other manufacturing processes.

Cost Efficient
The price-per-piece is significantly lower when compared with other processes. The final cost correlates with product quantity – greater quantities mean overall price decreases.

Time Efficient
We offer full lines of manufacturing and finishing services to make tools, allowing us to deliver superior quality molded parts within 10 days.

Wide Range of Material Selection
Choose from near-limitless plastic materials, Injection Molding produces high production runs of parts from a wide array of certified materials.

Scalability
Plastic Injection Molding is the perfect process for custom production 25-100,000 parts.

High Tolerances
Injection Molding is a highly automated production process that produce hundreds of thousands of finished identical parts with very details and accuracy dimension.

Injection Molding Process

Insert Molding
Insert molding is a great injection molding process that combine metal and plastics into one single part. It allows inserts such as helicoils, screws, metal filters to go inside your mold.

Overmolding
The overmolding is a multi-material injection molding process that allows clients to get the final item that involves two or more different types of material.

Mold Making
We offer design and manufacturing services for mold, dies, and tools to produce high quality plastic parts. Clients owe the tools.

Thermoplastic Injection Molding
LC Rapid produce custom injection molded items from hard toolings for low volume plastic molding and large runs of production.

Injection Molding Tolerance
The tolerance depends on the injection plastic, tooling structure, and the design geometry, injection molding part tolerance need to be discussed every project, we will attempt to meet your tolerance standard.
