Insert Molding
Pre-formed inserts are placed into the mold before plastic flows around them, creating a strong integrated component.
Overmolding
A second material is molded over a substrate to combine grip, sealing, impact protection, or cosmetic performance in one part.
Liquid Silicone Rubber Molding
Two-part liquid silicone is molded into flexible parts with high temperature, chemical, and durability performance.
Prototype Tooling Options and Quality Comparison
| Parameter | Original Data | China Supply Chain Data | Key Advantage |
|---|---|---|---|
| Typical Volume | < 2,000 | < 5,000 | Greater flexibility for low-volume production |
| Mold Cavities | Single | Single, with 1-4 cavity options available | Supports rapid iteration and multi-variant testing |
| Mold Life | Limited, 2,000 shots guaranteed | Limited, 10,000 shots guaranteed | More durable tools for larger validation runs |
| Mold Material | Aluminum | Aluminum or optional pre-hardened steel such as P20 | Better balance between cost and tool longevity |
Production Tooling Options and Quality Comparison
| Parameter | Original Data | China Supply Chain Data | Key Advantage |
|---|---|---|---|
| Typical Volume | N/A | > 50,000 units | Strong capability for mass production |
| Mold Cavities | Single and multi-cavity | Primarily multi-cavity, such as 1+1 or 2+2 | High production efficiency and lower piece-part cost |
| Mold Life | Unlimited | Typically 500K to 1M shots | Long tool life supports production stability |
| Mold Material | N/A | Standard pre-hardened steel, including P20 and 718H | Higher standard for dimensional stability |
Injection Molding Materials
Aiketek provides a practical selection of injection molding materials, from commodity plastics to specialty elastomers. Material selection is reviewed against performance, geometry, finish, and production volume.
PP (Polypropylene)
- Characteristics
- Excellent chemical resistance, electrical insulation, low moisture absorption, and low density. PP also performs well in repeated bending applications.
- Applications
- Automotive interiors, battery cases, consumer storage products, chairs, medical syringes, reagent bottles, and packaging materials.

Injection Molding Finishes and Post-Processing Options
Standard Finish
A practical moldmaker finish for non-cosmetic and internal surfaces, typically showing very light tooling marks.
Polished Finishes
SPI A, B, C, and D finish targets support high-gloss, satin, matte, or grit-blasted surfaces for appearance parts.
Production Appearance Control
Texture, gloss, gate location, and cosmetic faces are reviewed together before tooling is released.
VDI and Mold Texture
Texturing can improve grip, hide flow marks, and define the visual character of enclosure and handle surfaces.
Draft and Texture Depth
Texture depth is reviewed with draft angle so molded parts can release cleanly without damaging cosmetic faces.
Color and Resin Pairing
Material, pigment, gloss, and texture are checked together to reduce mismatch risk across production batches.
Painting and Decoration
Painting, pad printing, silk-screening, and marking are planned around masking, adhesion, and cosmetic requirements.
Assembly Operations
Heat staking, ultrasonic welding, insert installation, and packaging needs can be included in the manufacturing review.
Inspection Release
Samples, dimensions, and appearance standards are checked before repeat production is released.
Advantages of Injection Molding
- Low per-unit cost in mass production, with economical prototyping using aluminum molds.
- Excellent surface quality and dimensional stability for repeatable molded components.
- Capability for complex geometries while minimizing secondary processing.
- High material utilization with controlled rejection rates.

Frequently Asked Questions
What factors determine the cost of injection molding?
Injection molding cost is driven by mold fabrication, material, cavity count, cycle time, surface finish, and part complexity. Simplifying structures and improving wall thickness can reduce the total program cost.
Who owns the injection mold?
The customer typically owns the dedicated mold. Aiketek coordinates storage, maintenance, and production release around the agreed tooling scope.
Which industries commonly use injection molding?
Common programs include automotive parts, consumer electronics, medical devices, packaging, industrial equipment, and aerospace support components.
