In the automotive sector, tooling is more than just a mould — it’s the foundation of precision, efficiency, and product quality. At HH Plastic Metal, we pride ourselves on delivering world-class injection mould tooling that combines the cost-efficiency of Far Eastern manufacturing with technical rigour and project management. 

 Why Tooling Quality Defines Production Success 

Injection mould tools are the heartbeat of production. Poorly designed or built tools can lead to: 

• Dimensional instability (warpage, shrinkage, flash). 

• Excessive downtime from tool maintenance. 

• High scrap rates and rejected parts. 

• Costly delays during PPAP and production ramp-up. 

That’s why we approach tooling with an engineering-first mindset, integrating DFM (Design for Manufacture) principles, GD&T alignment, and long-term durability into every project. 

 

The HH Plastic Metal Approach 

Our tooling solutions are trusted across the automotive supply chain because we deliver: 

• Precision Engineering: Tools built to micron-level tolerances, ensuring consistent compliance with OEM dimensional requirements. 

• Advanced Materials & Treatments: Hardened steels, optimised cooling circuits, and wear-resistant coatings to maximise tool life. 

• Complexity Management: Multi-cavity, family tools, sequential valve gating, and integrated hot runner systems designed for high-volume, high-accuracy applications. 

• Mouldflow & Simulation: Every tool is validated through mouldflow analysis to predict fill, packing, cooling, and warpage before steel is cut. 

• Validation & Measurement: We integrate CMM inspection and checking fixtures into the tooling package to guarantee first-time-right approvals. 

 

Proven Benefits for Automotive Customers 

• Reduced Total Cost of Ownership: Lower upfront tooling costs, without sacrificing tool life or part quality. 

• Faster Time to Market: Efficient global workflows ensure tools are delivered on time and production-ready. 

• Assured Quality: Every tool meets OEM standards before shipment. 

• Long-Term Support: Local technical support and service, backed by Far Eastern production capacity. 

 

In summary:
At HH Plastic Metal, we don’t just manufacture tools — we engineer confidence into every mould. We provide a tooling service that delivers precision, durability, and value for the automotive industry worldwide.
