Injection Mold Tooling
Injection molds are crucial for mass-producing precise plastic molded parts. Made primarily from steel or aluminum, their creation involves intricate design, precise machining, and assembly.
Plastic Injection Molding
Plastic injection molding is a technique where molten thermplastic is forced into molds, solidifying into parts. Enabling efficient, and large-scale production with consistent quality.
Overmolding
Overmolding combines different plastic materials by molding one over another, enhancing functionality, aesthetics, and grip, while reducing assembly time and costs.
Insert Molding
Insert molding encases a pre-set insert with plastic, merging metal and plastic, enhancing strength, simplifying assembly, and ensuring precision integration.

Classes of Injection Mold
We adhere to the five standard categories of SPI mold classifications from Class 101 to 105, aligning expectations for customers and suppliers alike.
| Mold Class | Production Level | Cycles | Applications | Tolerance | Cost | Lead Time |
| Class 105 | Very low | Less than 500 cycles | Prototype testing | ± 0.02mm | Inexpensive to produce a very limited number of product prototypes | 7-10 days |
| Class 104 | Low | Less than 100K cycles | Good for limited-production parts with non-abrasive materials | ± 0.02mm | Fall within low to moderate price ranges | 10-15 days |
| Class 103 | Medium
|
Less than 500K cycles | For low to medium-production parts | ± 0.02mm | Fall within common price ranges | 10-15 days |
| Class 102 | Medium to high | Less than 1M | Good for parts with abrasive materials and/or tight tolerances | ± 0.02mm | Fairly high price and made with materials of high quality | 10-15 days |
| Class 101 | Extremely high | Over 1M cycles | Extremely high production and fast cycle times | ± 0.02mm | Highest price and made with only the highest quality materials | 10-18 days |
