GPTMOLD Mold Making Process: Precision, Efficiency & Versatility

GPTMOLD is renowned in the industry for crafting highly complex, high-productivity injection molds with superior craftsmanship. Our end-to-end mold making process—backed by skilled professionals and cutting-edge technology—ensures on-spec, accurate mold delivery, from initial design to final completion.

We specialize in a full range of mold solutions tailored to diverse requirements, with key capabilities summarized as follows:

• Mold Types: Single/bi-injection molds, standard molds with side actions & lifters, hot runner molds, unscrewing molds, and insert overmolds.
• Cavity & Class Options: Single to multi-cavity molds, covering SPI Class 101 (high-volume, long-life) to SPI Class 103 (general-purpose) standards.
• Press Compatibility: Molds适配 25-ton to 1000-ton injection molding machines, meeting large and small production scale needs.

Quality & compatibility are embedded in our process: We adhere strictly to DME and Hasco global mold standards. For the US market, we use inch-system components and offer renowned US-brand parts (Progressive, PCS, Parker, DME, etc.). Our molds are built with premium materials from trusted suppliers (Diado, Assab/Uddehom/Bohler, Thyssen) and can integrate hot runner systems (Yudo, Husky, DME, Moldmaster, Synnventive, Incoe) per customer specifications.

Core Mold Making Process Stages

Our streamlined, quality-controlled process ensures consistent mold performance, with key stages in cards below:

Our streamlined, quality-controlled process ensures consistent mold performance:

• Precision Machining: Leveraging advanced CNC machining centers, EDM, and wire-cutting technology to achieve micron-level accuracy for mold cores and cavities, laying the foundation for high-precision parts.
• Modular Assembly: Following standardized assembly procedures, our technicians meticulously fit components (guides, sliders, hot runners) to ensure smooth operation and interchangeability of parts.
• Rigorous Testing & Trial Run: Conducting mold trial injections with target materials to verify filling uniformity, cooling efficiency, and ejection stability. Defects are addressed promptly before final delivery.
• Final Inspection & Packaging: Comprehensive quality checks on dimensional accuracy, surface finish, and mechanism performance. Molds are packaged with anti-rust treatment for safe transportation.

Key Performance Indicators (KPIs)

• Mold Life: SPI Class 101 molds support over 1 million injection cycles; SPI Class 103 molds meet 500,000+ cycles, ensuring long-term production reliability.
• Delivery Time: Standard molds delivered in 25–45 days; custom complex molds in 45–60 days, balancing speed and quality.
• Precision Tolerance: Achieves ±0.001mm dimensional accuracy, suitable for high-demand applications like optical lenses and automotive components.
