New Energy

The mold processing of Haina Company has also achieved some success in the field of new energy. In recent years, Haina Company has provided mold design and development services to our unmanned aerial vehicle company clients and has achieved mass production. It has now become a first-level agent for this company. It provides dual-color injection molded battery trays for companies such as BYD and Tesla. It adopts a one-time molding technology of hard rubber + soft rubber, and the single order amount is nearly 50 million yuan.

Core technical capabilities

1. High safety standard structural design

• Insulation structure design: For high-voltage components, an "projection + groove" creepage distance optimization structure can be designed, with tolerances controlled within ±0.1mm, meeting the withstand voltage requirements above 5000V

• Thin-walled lightweight: Supports 2-2.5mm thin-walled molding, and the honeycomb-shaped strengthening rib design can reduce weight by 20% while improving stiffness by 15%

• Heat dissipation structure integration: Precise micro-fin plate forming technology, with fins as thin as 0.8mm and a spacing of 2mm, effectively improving heat dissipation efficiency

2. High-reliability Materials and Processes

•Flame-retardant material compatibility: Familiar with the molding process characteristics of flame-retardant V-0 grade materials such as PA66 + GF30, PBT, and PC/ABS

•Corrosion-resistant material treatment: Using S136 high-purity mold steel, PVD/TiN coating treatment can be applied to key areas, and the mold service life can reach over 300,000 cycles

•Insert molding technology: Supports integrated molding of metal inserts, and the offset of the inserts can be controlled within ±0.05mm

3. High-precision Molding Assurance

•Mold flow analysis optimization: Through Moldflow simulation analysis, precisely control the uniformity of wall thickness and the layout of reinforcing ribs to prevent sealing failure due to shrinkage

•Form-following cooling technology: Integrating 3D printing form-following cooling waterways, the cooling efficiency can be increased by 30-40%, and the dimensional tolerance of large-sized shells can be controlled within ±0.1mm

•Precision processing capability: Five-axis machining center has a positioning accuracy of ±0.005mm, combined with three-coordinate full inspection, and 100% inspection of key dimensions
