Industrial Parts Container Mold - Yige Precision Molding Technology Solution

I. Core Technical Features

Industrial parts container molds are essential equipment in logistics warehousing, manufacturing, and food processing industries, used for producing integrated plastic tote boxes with pallets. Yige Molds possesses the following core technical features in the manufacturing of industrial parts container molds:

1. High-Precision Molding Capability

Utilizing five-axis machining centers for precision processing, cavity accuracy is controlled within ±0.02mm, ensuring dimensional tolerances at the mating parts between tote boxes and pallets are kept to a minimum. Through high-speed milling and EDM processes, high-precision forming of complex reinforcing rib structures is achieved, with wire-cutting machining accuracy reaching ±0.005mm. Positioning slot dimensions at the AGV lifting mechanism interface achieve ±0.1mm accuracy, ensuring seamless integration with automated logistics equipment.

2. Safe and Environmentally Friendly Material Selection

Mold materials prioritize food-grade 718H pre-hardened steel and S136 stainless steel, ensuring products are non-toxic and odorless, compliant with RoHS environmental standards. Surface treatment processes achieve cavity roughness of Ra≤1.6μm, enhancing product surface finish. After vacuum quenching, material hardness stabilizes between HRC52-56, providing excellent wear resistance and thermal fatigue performance.

3. Precise Thermal Management System

Molds are equipped with zoned temperature control and efficient cooling systems, maintaining cavity temperature differences within ≤±2°C, ensuring molding efficiency and product quality. The cooling system adopts conformal cooling technology, using 3D printing to create cooling channels, improving cooling efficiency by approximately 30% and shortening molding cycles by nearly 25%. Water channel spacing is controlled at 20-30mm, ensuring uniform cooling of large tote box structures and preventing warping deformation.

II. Key Design and Processing Technologies

1. Scientific Material Compatibility

Based on product requirements, high-quality mold steels such as P20, 718H, and 2738 are selected, with hardness controlled between HRC33-62 to balance wear resistance and machinability. The material system uses pre-hardened 718H mold steel (HRC 36-38) paired with carbide inserts. For high-frequency friction areas like sliders and core pins, tungsten steel inserts with surface nitriding treatment (hardness above HV900) are used, maintaining smooth mold surfaces during long-term demolding.

2. Structural System Optimization

• Multi-point synchronized ejection system with ejection pin density of at least 2 per 100cm², ensuring smooth demolding of large tote boxes

• Optimized exhaust system design with vent hole dimensions set at 0.03-0.05mm, preventing defects like bubbles and shrinkage porosity

• Conformal cooling system design with water channel spacing controlled at 20-30mm, improving cooling efficiency

• "Avoidance layout" parting surface design addresses common issues like unstable stacking and handle breakage in tote boxes by adjusting parting lines from stress areas to non-stress areas, avoiding flash residue

3. Precision Machining Process

Utilizing advanced processes such as high-speed milling and EDM, high-precision mold manufacturing is achieved. Surface polishing combined with nitriding processes reduces cavity roughness to Ra≤0.08μm, enhancing product surface finish. PVD coating technology extends mold lifespan beyond 800,000 cycles. After 500,000 cycles of continuous use, cavity wear is only one-third of the industry average, significantly reducing mold maintenance frequency.
