Multi-Shot Molding (2K/3K/Multi-Component) Injection Molds

1. Core Technologies

GPT Mold leverages advanced engineering to handle complex multi-material requirements:

• Rotary Table & Core-Back Technology: Expertise in utilizing Rotary Table (2K Rotary Mold) und Core-Back mechanisms to achieve precise material transition in a single molding cycle.

  Reverse Ejection Systems: Implementation of Reverse Ejection to manage intricate part geometries and ensure smooth de-molding of multi-layered components.

  High-Precision Tooling Fabrication: Using state-of-the-art Japanese Makino CNC und Sodick EDM machines to ensure tight tolerances (+/- 0.01mm), preventing material “flashing” oder “bleeding” between shots.

  Optimized Hot Runner Systems: Integration of premium hot runner brands (z. B., Moldmaster, Husky, Yudo) to precisely control melt temperature and flow for each independent material shot.

2. Customer Concerns & Lösungen

We address the most critical pain points for our global clients:

• Materialkompatibilität: We conduct deep MoldFlow Analysis to evaluate the chemical bonding and thermal expansion between different resins (z. B., hard plastics to soft TPE/TPU).

  Dimensionsstabilität: Addressing potential shrinkage and warpage issues in complex Stack Molds or large-scale multi-shot parts through rigorous DFM (Design for Manufacturing) reviews.

• Effizienz & Zykluszeit: Customers demand high-volume productivity. Our designs focus on optimized cooling channels to reduce cycle times without compromising part quality.

  Quality Consistency: We provide full CMM dimension reports and strictly follow ISO 9001 standards to ensure every shot meets the customer’s exact specifications.

3. GPT Technical Advantages

• Extensive Experience: Proven track record in complex automotive projects, including 2K Rotary Molds for interior/exterior trims and precision Reflex Lens Molds.

  One-Stop Engineering: From initial DFM and MoldFlow analysis to in-house injection trials (60T to 2500T trial capacity) and secondary operations like electroplating.

  Global Standards: We strictly adhere to DME and HASCO mold standards , ensuring our multi-shot tools are easily maintained by our clients in the USA and Europe.

  Advanced Equipment: Our CNC Room is equipped with high-speed Japanese machines like MAKINO V33i and F5 specifically dedicated to precision mold inserts.

4. Typical Solutions

• Automotive Interior/Exterior: 2K rotary molds for multi-color buttons, door handles, and lighting components with high-gloss surface requirements.

• Precision Sealing: Overmolding solutions that integrate soft-touch gaskets directly onto hard structural housings for medical or industrial applications.

  Complex Structural Molds: Utilizing Collapsible Cores (S-core) and multi-material shots to reduce the need for secondary assembly, significantly lowering overall production costs
