Quality and Reliability

Quality and Detail

The high pressure involved in Injection molding means that the molten material penetrates the nook and cranny of the mold before solidification and curing. This allows engineers to design complex parts, inscriptions, details, and elements into their part with the assurance that every part will be made just as they imagined.

Scalability and repeatability

Scalability and repeatability

Injection molding can produce thousands to millions of parts that are exact and identical to the master mold tooling.

Cost-reduction

Cost-effectiveness

An Injection molding tool made from steel can make hundreds of thousands of parts, spreading the tooling cost over a large volume and ultimately lowering the cost-per-part.

Material Quality

Material diversity and options

Injection molding is the most diverse manufacturing technique when it comes to material selection and considerations. Injection-molded parts can be made even stronger by using fillers and composite materials into the liquid resin to improve its tensile strength.

Finishing solutions

Low-volume manufacturing

Aluminum tooling lower setup and tooling costs, ensuring that injection molding can be used for rapid prototyping and low-volume manufacturing.

Custom Surface Finishes

Custom Surface Finishes

With the proper process optimization techniques, injection molded parts can be ejected ready-to-use or finished in an array of popular or custom methods to ensure that your part look and feel as intended.

Our entire injection molding capabilities include insert molding, mold making, rapid tooling, and overmolding.

Overmolding

1_0001_图层 2

Overmolding is an injection molding operation that is used to make a single part from multiple materials. At First Part, we can mold a thermoplastic material into a second material to leverage certain performance and characteristic attributes of the materials to complement functionality. An example is the solid plastic body and rubberized handles of toothbrushes. Overmolding is very effective for creating composite parts, costing lesser than other production techniques that require assembly of separate components.

Insert Molding

1_0002_图层 5

Insert molding is one of First Part’s injection molding capabilities, enabling us to create or integrate plastic fragments and components (inserts) to the pre-fabricated metal part. Through our expertise in cross-technology fabrication, we can use sheet metal and CNC machining to make units of your metal part and employ insert molding to introduce plastic parts. Insert molding can be used in making tools that are sharp and require a grip. Examples include scalpels, fasteners, bushings, or clips.

Injection Molding Applications

First Part Injection Molding Operations can be applied in:

High-functional end-part production

· High-functional end-part production

Injection molding is widely used in making functional end-use parts that will replace metal parts in most components. Choose from materials to finishes to make high-quality parts that are of high strength and less weight than metal counterparts.

Rapid tooling

· Rapid tooling/Mold making

We can use our optimized injection molding process to manufacture molds, tooling (cores and cavities), and dies for use in making any range of budget, volume, and production times.

Rapid Prototyping

· Rapid Prototyping

Take advantage of low-cost tooling options to allow you to make highly-functional parts that are suitable for functionality testing. Even when tooling with aluminum molds, our injection molded parts are almost certain to outperform 3D printed or CNC machined parts from the same material. A low-cost mold can be made in a shorter window, and depending on size and geometry, it could be used in making many volumes. (up to thousands of prototypes)

What Is Plactic Injection Molding?

Plastic injection molding is the most widely-used manufacturing technique for the production of mass units of plastic parts that serve industrial and commercial purposes. Plastic injection molding also has the highest range of materials, color, and configuration when put side-by-side with processes like CNC machining or Additive manufacturing.

The process essentially involves the injection of molten plastic material (resin) under high pressure into the cavity of a metal die before cooling the mold to solidify the shape into its final part. Depending on the part size, material, and design complexity, the injection molding cycle may span anywhere from a few seconds to a couple of minutes. 

Plactic Injection Molding

In First Part China Limited, we can handle the plastic injection molding rapid tooling for both high-volume and low-quantity parts production. Using the technical maturity to produce high quality custom plastic molded parts for defense, automotive, medical, aerospace and consumer products.

Our Plastic Injection Molding Process

At First Part, we design our plastic injection molded parts in 6 quality-driven steps:

1.Material preparation

Dry plastic pellets may be used as they come or blended with colorants or fillers.

2.Loading

The pellets are loaded into the hopper of the molding machine and transported by a screw in the barrel towards the mold.

3.Heating

The dry pellets are then heated inside the barrel of the machine until they form the liquid resin, in a fully molten state. The mold is also heated.

4.Injection

The molten resin is injected under high pressure into the heated mold cavity through a gate. The resin fills the cavity and takes the form of the mold tool.

5.Ejection

The cooled and now-solid part is ejected into the loading bin by opening the mold. Ejector pins aid the removal of the part from the mold. A new injection molding cycle may now commence.

6.Cooling

The mold is cooled to solidify the part within.
