YIXUN mold
8480419090
Realizes uniform melt filling for large rectangular flat base boxes, effectively eliminating warpage, shrinkage dents and visible weld lines, ensuring excellent flatness for precise assembly.
No cold runner waste, automatic gate cutting during mold opening, no manual trimming or secondary polishing required, greatly cutting labor cost and shortening molding cycle for high-volume automated production.
Independent temperature control of hot runner nozzles prevents ABS material degradation, yellowing, silver streaks and bubbles, guaranteeing consistent surface quality of finished products in long-time continuous molding.
Cavity Material: S136R, HRC 42~44 Pre-hardened Stainless Steel
Excellent corrosion resistance against corrosive gas generated from ABS high-temperature melting, effectively avoiding mold rust during long-run production. It supports precise texture etching, delivering scratch-resistant, fingerprint-proof and high-grade surface texture for the outer shell of base boxes, with stable texture effect after hundreds of thousands of molding shots.
Core Material: 2083, HRC 42~44 Pre-hardened Mold Steel
Superior polishing performance for high-gloss finishing on the core surface, ensuring smooth ejection without product scratch, whitening or deformation. Uniform hardness endures long-term high injection pressure, reduces mold deformation risk and maintenance frequency.
Cavity (Front Mold): Texture Etching
The textured outer surface hides tiny molding defects, improves wear resistance and anti-slip property, upgrading the industrial appearance of electronic base boxes.
Core (Rear Mold): High Gloss Polishing
Smooth inner surface guarantees stable dimensional tolerance of mounting holes and positioning structures, ensuring high assembly precision for internal circuit boards and electronic components.
Strictly adopts ABS shrinkage rate of 1.005 for cavity size calculation, combined with pre-mold flow analysis, realizing high dimensional consistency and strong interchangeability between GR17 and GR19 two-specification base boxes.
1×1 single cavity layout features simple mold trial and parameter debugging, flexible to match small-batch trial production and mass bulk orders, lowering production downtime and adjustment cost.
The two molds adopt unified structural design, gating scheme and steel standard, which can greatly shorten the development cycle and R&D cost when expanding other sizes of R10 series base boxes in the future.
