Injection Mold Manufacturing Services
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
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
Step 2: The pallets are 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 Precision 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 SelectionWide 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.

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

High TolerancesHigh 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.

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

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

End-use Production
Injection molding is the most commonly used manufacturing processes used to
create end-use production plastic parts as the tool can produce thousands of
high quality parts per day. Injection molding is well known for producing
products as a mass scale with speed, quality consistency and low price-per-

Rapid Prototyping
Injection molding is ideal for rapid moulding prototyping because the molded
parts can be produced efficiently and cost effectively to test and validate a
concept model. Generally speaking, the molded parts of rapid injection molding
prototyping have more toughness and greater impact resistance than 3D printed

Injection Molding FAQ
Do you offer multi-cavity tools?
We are able to make multi-cavity tools for injection molding to reduce the
tooling cost and production costs.

Can I modify the injection mold after the first run?
Whether your injection mold needs additional machining, welding, or replacement
of hoses and small parts, we can modify for your at a reasonable cost. However,
it is more cost-saving to produce a new mold than modifying the existing one if
the changes are a lot.

How to select resigns for injection molding?
Customs should take the performance of various resin types and grades into
consideration, which including tensile strength, impact strength, mechanical
characteristics, molding properties, and cost of the resin.

What materials do you use for the molds?
We use aluminum and steel material to fabricate the molds. LC Rapid specializes
in low-cost, rapid turnaround tooling for around 50,000 cycles. Toolings for
around 50,000 cycles is advantageous especially for prototyping and low-volume
production products where low-cost is significant.
