Plastic Injection Molding Services

Premium Injection Molded Parts We Did

On Demand Injection Molding Services

From prototype to mass production, by using our on-demand manufacturing services, you can get the most cost-effective solution at every stage.

Low-Volume Injection Molding

Short-Run (Low Volume) Injection Molding is a specialized service that provides a bridge between initial prototypes and high volume injection molding. Our Short run molding is ideal for small businesses or small-batch manufacturing, it can shorten your lead time, help you access new markets rapidly.

High-Volume Injection Molding

Injection molding is the best way for the mass production of plastic parts, because it can reduce unit costs and cycle time, it can ensure accurate and consistent parts. We offer specialized high volume injection molding service, can produce premium quality parts in volumes of up to millions of pieces a month.

Our Injection Molding Capabilities

Our various kinds of injection machines, experienced engineers team can support all your needs, from prototype to mass production.

Rapid Tooling

Rapid Prototype Tooling

Rapid prototype tooling uses aluminum inserts to make the tool. This method is only for small quantities, providing design flexibility, reducing the mold cost and cut down lead-time to around 1-2 weeks.

Production Tooling

Production Tooling

Ideal for mass production of plastic injection molding parts. Tooling costs are higher than rapid tooling but has significantly cost per unit. The lead-time for production tooling usually takes around 3-4 weeks.

Family Molds

Family Molds

Family molds reduce tooling cost by accepting dissimilar shapes into the same mold. This process is ideal for intermediate-volume prototypes of various shapes by leveraging the manufacturing efficiency of molding with the flexibility of custom tooling

Single Cavity Molds

Single Cavity Molds

Molds containing only one cavity, producing one unit per run.

Multi-cavity Molds

Multi-cavity Molds

Best for high-volume, repeatable parts, multi-cavity molds contain identical cavities to increase throughput and achieve a lower favorable per-unit cost.

Overmolding

Overmolding

An existing molded part is installed in the mold, then covered with new material. This two-step process enables multi-material part design flexibility by creating molds with dissimilar materials of construction

Insert Molding

Insert Molding

Inserts are placed into the mold and molding occurs around them. This allows for inserts such as helicoils to be molded in your design.

Part IMD & IML

Part IMD & IML

In-mold decoration (IMD) and in-mold label (IML) are used to create a visually extraordinary permanent appearance with graphics or labels. A variety of textures, colors and surface coatings are available, providing the possibility for innovation.

Available Surface Finishes Class

Smooth and glossy finish plastic part

Smooth and glossy finish

If your plastic parts require the smoothest finish, SPI grades A1, A2 and A3 are recommended. The molds in these grades will use hardened tool steel, the surface of the mold is polished by grit diamond. The mirror gloss provides a smooth gloss almost like a mirror. Products such as sun visors, plastic mirrors and optical products are made using such finishes.

Semi-glossy finish plastic part

Semi-glossy finish

If your plastic parts require the Semi-glossy finish, SPI grades B1, B2, and B3 are recommended, the semi-glossy finish is a good way to remove the processing, tooling marks. In the mold with a semi-glossy finish, grit paper will be used for grinding.

Matte finish plastic part

Matte finish

For plastic products that need a matte finish, we recommend SPI grades C1, C2, C3. The mold used for the matte finish is polished with gritstone. Matte finish is widely used in industrial parts, consumer goods, and other fields.

Textured finish plastic part

Textured finish

SPI grades D1, D2, and D3 are recommended if the part requires a textured finish. Molds for textured finishes are first ground with the dry blast and then dry sprayed with alumina and sometimes glass beads. A textured surface provides a good grip quality, conceals deformations and traces, and sometimes even helps to mask fingerprint stains.

Additional Finishing and Coating Options

Finishing or coating is applied after machining and can change the appearance, surface roughness, hardness, and chemical resistance of the produced parts.
