Manage Your Machining Needs with MachMaster

Types of Injection Molds

We support a wide range of part geometries, volumes, and design complexities—offering flexible molding solutions to match your material, performance, and production needs.

Single Cavity Mold

Used for lower-volume production or prototyping where speed, cost control, and design validation are priorities.

Multi Cavity Mold

Produces multiple identical parts in each cycle, reducing per-unit cost and increasing overall throughput for medium to high volumes.

Family Mold

Allows different part geometries to be molded in a single cycle—ideal for assemblies or parts sets with shared material requirements.

Insert Molding

Combines molded plastic with preformed components such as metal pins, threads, or bushings—enhancing part strength and functionality.

Materials for Injection Mold Tooling

Choose the right mold material to balance durability, cost, and production volume.

Cost-effective and easy to mold, materials like ABS, PP, and PS are commonly used in enclosures, housings, and consumer products.

Materials such as PC, PA, POM, and PBT provide high strength, heat resistance, and dimensional stability for functional parts.

PC, PMMA, and PETG offer clarity and optical-grade surface quality—ideal for lenses, windows, and cosmetic components.

TPU and TPE are elastomeric materials used for overmolding, seals, and grip-enhanced parts requiring flexibility and durability.

For demanding environments, we support materials like PEEK, PPS, and reinforced nylon—excellent for high-temp and chemical resistance.

Surface Finishing Options for Injection Molded Plastics

Injection molded plastic parts can be enhanced with post-processing techniques or molded-in textures. These finishes improve product aesthetics, usability, and brand presentation.

Silk Screen Printing

Silk screen printing is widely used to apply logos, icons, or instructional text onto molded plastic parts. It supports multiple colors and curved surfaces, offering excellent adhesion and durability.

✔ Suitable for brand logos, labels, and patterns
✔ High clarity, abrasion-resistant prints
✔ Common in consumer electronics, packaging, and appliances

Spray Painting / Coating

Spray coating enhances both the appearance and protective properties of plastic parts. It allows for a variety of finishes, including matte, glossy, soft-touch, and metallic effects.

✔ Applied post-molding under dust-controlled conditions
✔ Custom color matching with RAL/Pantone support
✔ Ideal for cosmetic packaging, automotive trim, and home goods

Electroplating

Plastic electroplating adds a metallic finish to plastic parts while improving surface hardness and visual appeal. Vacuum plating is preferred for uniform and eco-friendly results.

✔ Chrome, nickel, or custom finishes available
✔ Requires base coating + activation process
✔ Used in automotive interiors, household appliances, and luxury packaging

SPI Mold Finish

The final surface texture of a molded part is often defined by the SPI (Society of the Plastics Industry) mold finish. This determines gloss level directly from the mold—no post-processing needed.

✔ SPI A1–A3: mirror gloss (polished)
✔ SPI B1–B3: semi-gloss (paper polish)
✔ SPI C1–C3: matte (stone finish)
✔ SPI D: textured/rough (dry blast)
✔ Eliminates need for secondary finish in many applications

FAQs About Plastic Injection Molding

What Is Plastic Injection Molding?

Plastic injection molding is a manufacturing process that involves injecting molten plastic into a steel or aluminum mold to form parts with complex shapes and tight tolerances. It’s ideal for producing high volumes of identical components with excellent repeatability.

What Types Of Plastic Materials Are Available?

Common materials include ABS, PC, PP, POM, PA (Nylon), PE, PET, PS, and more. Each material offers different benefits such as heat resistance, flexibility, chemical resistance, or mechanical strength.

How Long Does The Injection Molding Process Take?

Once the mold is ready, injection molding cycles are very short—typically a few seconds to a couple of minutes per part. Mold fabrication time varies based on complexity and ranges from a few days to several weeks.

What Tolerances Can Be Achieved With Plastic Injection Molding?

Standard tolerances are ±0.1 mm, but tighter tolerances are possible with proper mold design, material selection, and processing controls.
