What Are Custom Injection Molding Services?
Custom injection molding services manufacture plastic parts by injecting molten resin into precision molds. This process is ideal for high-volume production with high repeatability and tight tolerances.
Connectors & Housings
Diagnostic Devices
Chargers & Wearables
Gears & Enclosures
Injection Molding Capabilities
Comprehensive solutions ranging from low-volume prototyping to high-speed mass production.
Prototype Molding
Ideal for product validation, functional testing, and pilot runs before committing to hard tooling.
- Best For: Product Validation
- Quantity: 50 – 1,000 pcs
- Tooling: Soft / Aluminum Mold
Production Molding
High-volume manufacturing using hardened steel molds for maximum durability and precision.
- Best For: Stable Long-Term Supply
- Quantity: 100,000+ pcs
- Tooling: Hardened Steel (P20, S136)
Insert Molding
Integrating metal or other components into the plastic part during the molding process to reduce assembly.
- Apps: Metal Inserts
- Apps: Threaded Components
- Apps: Electrical Connectors
Overmolding
Combining two or more materials into a single part to improve grip, feel, or functionality.
- Apps: Soft Touch Grips
- Apps: Medical Devices
- Apps: Hand Tools

Frequently Asked Questions
What is the minimum order quantity (MOQ)?
▼
Our MOQ is typically 100 pieces depending on the existing tooling availability. For new custom projects, we can start with prototype quantities as low as 50 units using soft tooling.
How long does it take to build a mold?
▼
Standard production molds take 25-35 days. Rapid prototype molds (soft tools) can be ready in 7-15 days.
Can you provide DFM feedback?
▼
Yes, we provide complimentary DFM (Design for Manufacturing) analysis upon receipt of your 3D files. This includes suggestions on draft angles, wall thickness, and gate locations.
Do you support medical-grade materials?
▼
Absolutely. We work with ISO13485 compliant materials such as PC, ABS (Medical Grade), PEEK, and Liquid Silicone Rubber (LSR).
