Stable Large-Size Product Molding Hot Runner Etching Texture Plastic Box Frame Plastic Mold

Key Features

1. Stable Large-Size Molding Structure Design

• Built with heavy-duty high-rigidity mold base and multiple precision guide pin assemblies, effectively resisting high injection pressure during large-size part molding to prevent mold expansion, deformation and dimensional offset in long-term continuous production.

• Internal reinforced rib structure design of the plastic box frame is perfectly reproduced via precision CNC and EDM machining, greatly improving the load-bearing capacity and structural stability of finished box frames, avoiding bending or cracking under heavy load.

• Optimized balanced circulating cooling channels uniformly control mold temperature, effectively solving common defects of large plastic parts such as warpage, shrinkage and uneven deformation, ensuring consistent dimensional accuracy within ±0.02mm.

2. Advanced Hot Runner Feeding System

• Equipped with professional hot runner manifold and temperature-controlled nozzles, eliminating cold runner waste materials to greatly reduce raw material consumption and production cost for large-size plastic products.

• Multi-point balanced gating layout ensures uniform melt filling across the entire large cavity, effectively removing weld lines, short shots and flow marks, significantly improving the surface quality and mechanical strength of the plastic box frame.

• Independent temperature control for each hot runner zone allows precise parameter adjustment for different engineering plastics, adapting to PP, ABS, PC, flame-retardant PC/ABS and other industrial raw materials.

3. Customizable Etching Texture Surface Treatment

• Mold cavity supports professional VDI texture etching, matte grain and anti-slip surface processing, replacing secondary painting or spraying procedures to lower post-processing costs.

• The textured surface effectively resists daily scratches, friction marks and fingerprint residues, greatly improving the wear resistance and industrial-grade appearance of the plastic box frame.

• Various texture grades are optional to meet different design requirements of industrial equipment, household appliances and automation products for anti-slip, dust-proof and decorative appearance.

4. Long Service Life & Strict Quality Control

• Optional high-grade pre-hardened mold steel such as NAK80 / 718H / S136, with excellent wear resistance, corrosion resistance and texture replication performance, standard service life reaches 600,000~1,000,000 shots.

• The whole machining, assembly and trial production process follows ISO9001 quality management standards, with complete dimensional inspection records, raw material certification and process traceability files provided for factory audit and export clearance.

• Pre-reserved precise assembly holes, positioning grooves and limit buckles on the plastic box frame, realizing seamless installation with internal circuit modules, brackets and other components.
