Injection Molding Process

We are committed to delivering custom injection molding solutions for our customers, covering a spectrum of services
such as plastic injection molding, insert molding, and overmolding. Utilizing innovative processes and state-of-the-art
equipment, we are capable of producing molded components that meet your rigorous standards within remarkably short lead times.

Plastic Injection Molding

Plastic injection molding involves injecting molten thermoplastic into a mold, where it cools and solidifies into parts. The process enables mass production of intricate and complex parts with high precision.

Overmolding

Overmolding combines two or more materials by molding one plastic material over another, creating an integrated part. It allows for creative and functional designs.

Insert Molding

Molding a metal or plastic component into a thermoplastic material to create a single, integrated part. It allows for the combination of different materials, enhancing the structural integrity and functionality of parts.

Bi-color Injection Molding

Bio-color injection molding allows the production of plastic parts with two different colors or materials in a single molding cycle. This process enables the creation of intricate and visually appealing components.

Injection Molding Tolerance

For non-critical applications, such as for some consumer products, the tolerance for injection molded parts is typically ±0.1mm. For applications that require tighter tolerances, such as injection molded medical parts, ±0.025mm is typical.
The molds will be CNC machined to standard tolerances of ±0.125mm (±0.005") after adjusting for part shrinkage. Tighter tolerances can be requested and may increase the cost of tooling.
Part-to-part repeatability is typically under 0.100mm(0.004").
Unless otherwise specified, all quotes are based on the assumption that standard injection molding equipment will be used. If special tooling configurations are required, they must be expressed during the quoting process.

Injection Molding Materials

SogaWorks offers an extensive range of plastic materials for your injection molding projects,
which brings you multiple material options to complete prototypes and production runs of custom parts.

Thermoplastics

Polymer that can be melted and re-molded multiple times without undergoing significant chemical change.
These materials mainly include:
- ABS
- ABS/PC
- HDPE
- LDPE
- PA(Nylon)
- PBT
- PC
- PC/PBT
- PEEK
- PEI
- PET
- PETG
- PP
- PPS
- PS
- PMMA (Acrylic)
- POM (Acetal/Delrin)

Surface Finishes

We offer a variety of high-level surface finishes and only some common finishing
options are listed as below. There are more finish options for custom injection molding parts.

Painting

Painting is a common method used for applying a protective or functional coating to surfaces. It involves the application of liquid paint and then undergoes a curing process to solidify the paint film.

Silk Screen

Silk Screen is a printing technique used in CNC machining to apply images, patterns, or text to surfaces.

Laser Marking

Laser marking is a method to label, engrave, or add information to materials. It involves using a laser beam to alter the surface of the workpiece, creating visible marks without physical contact.
