Advanced 2-Shot Mold
Manufacturing Experts
Delivering high-precision, multi-material injection molding solutions. From in-house 24H DFM analysis to T1 samples in 15 days, we engineer reliability into every component.
Mastering the Complexity of
2-Shot Injection Molding
Two-shot molding (or dual-shot) is an advanced manufacturing process that molds two different plastic resins into a single, integrated part within one machine cycle. This technology eliminates secondary assembly, enhances product durability, and allows for complex ergonomic designs.
-
Cost & Time Efficiency
Eliminates post-molding assembly steps, significantly reducing labor costs and cycle times.
-
Superior Bond Integrity
Chemical and mechanical bonding between materials ensures optimal part strength and longevity.
-
Enhanced Aesthetics & Function
Combine rigid substrates with soft-touch overmolds or multi-color combinations effortlessly.

Trusted by Global Brands & Utilizing Premium Resins
Material Compatibility in 2-Shot Molding
The success of a two-shot injection molded part relies heavily on the chemical and mechanical compatibility of the chosen resins. If materials do not bond properly, the part will fail in the field. At GBM Mold Technology, our material scientists work closely with your design team to select the optimal substrate and overmold combinations.
Common Successful Combinations:
- PC + TPU/TPE: Excellent for rigid structural components requiring a soft, ergonomic grip (e.g., power tools, medical devices).
- ABS + TPE: Cost-effective solution for consumer electronics and household appliances.
- PC + LSR (Liquid Silicone Rubber): The gold standard for medical applications requiring sterilization and superior sealing.
Beyond chemical adhesion, factors such as melt temperature, shrinkage rates, and wall thickness must be precisely calculated during the mold design phase. Our proprietary DFM process simulates these variables to ensure dimensional stability and zero defect rates in mass production.
Frequently Asked Questions
Find answers to common technical queries regarding our tooling processes, lead times, and engineering capabilities.
Ask a Technical QuestionDepending on the complexity and size of the part, standard lead times for T1 samples range from 4 to 6 weeks. However, with our expedited in-house tooling capabilities, we can achieve T1 in as little as 15 days for specific project requirements.
Yes, absolute. We provide a comprehensive DFM analysis within 24 hours of receiving your 3D CAD files. This includes mold flow analysis, draft angle verification, wall thickness checks, and material compatibility suggestions to ensure successful 2-shot molding.
Our facility is equipped with dedicated 2-shot injection molding machines ranging from 120 Tons to 800 Tons, featuring rotary platens and index plates to accommodate various mold sizes and part geometries.
Yes, over 70% of our molds are exported to North America and Europe. We strictly adhere to SPI, HASCO, and DME standards, using premium mold steel (e.g., Assab, Schmolz+Bickenbach) to guarantee mold life up to 1,000,000 shots.
