Stable Temperature Control 1*1 High Gloss Polish Cavity ABS Structural Bracket Plastic Mould

This custom injection mold is developed for mass production of ABS structural bracket. Adopting XF-2083H pre-hardened mold steel with uniform hardness of HRC30-36 for both cavity and core, this single-cavity mold is equipped with a single point needle valve hot runner system, perfectly matched to ABS material shrinkage rate of 1.005. The finished product adopts PANTONE PQ-420C off-white color with high-gloss surface, widely used in household appliances, office automation equipment and intelligent devices as internal fixing and load-bearing structural support. We provide one-stop mold customization service including mold flow simulation, precision CNC machining, high-gloss cavity polishing, multiple rounds of mold trial and global after-sales technical support.

Core Mold Advantages

1. XF-2083H Pre-hardened Mold Steel, Stable HRC30-36 Hardness

• Uniform internal metallurgical structure, low internal stress, effectively avoids mold deformation during long-term continuous high-pressure injection

• Excellent high-gloss polishing performance, perfectly achieves bright defect-free surface for off-white ABS products, meets high-end appearance requirements

• Good corrosion resistance and wear resistance, effectively prevents color contamination during frequent color switching production, ideal for large structural bracket long-cycle molding

• Standard service life reaches 600,000 to 1,000,000 shots, greatly reducing later mold maintenance and replacement cost

2. Single Point Needle Valve Hot Runner Gating System

• Precise valve gate control ensures stable melt injection pressure, realizes balanced filling for large-size irregular cavity, eliminates short shot, weld line, sink mark and flow mark defects on thick-wall positions

• No cold runner waste, saves a large amount of ABS raw material cost, cancels post-manual runner trimming procedure, improves production automation and product yield

• Stable mold temperature distribution effectively reduces internal stress of ABS structural parts, avoids bracket warpage, bending and dimensional deviation after molding

• Convenient for parameter adjustment during mass production, compatible with automatic continuous injection molding production line

3. 1×1 Single Cavity Design for Large Precision Structural Parts

• Ensures uniform clamping force distribution during injection, effectively prevents mold deflection caused by unbalanced pressure, guarantees long-term dimensional tolerance stability of mounting holes and positioning structures

• Facilitates the layout of circulating cooling channels and dense exhaust slots around ribs, holes and deep cavity positions, fully solves gas trapping defects of thick-wall ABS parts

• Convenient for mold debugging and sample verification, effectively shortens trial production cycle and reduces molding defect rate of complex structural products

4. High Consistency for PANTONE PQ-420C Off-white Color Matching

• Smooth mirror surface avoids material residue adhesion and color migration, ensuring batch color uniformity without yellowing or discoloration

• Optimized mold temperature control system avoids local overheating of ABS material, prevents product surface yellowing and chromatic aberration during mass production

• Meets strict appearance inspection standards of home appliance and office equipment, no secondary spraying required after molding

Application Scope

• Household appliances internal load-bearing fixing brackets and mounting bases

• Printers, scanners, copiers and other office equipment structural supports

• Intelligent terminal equipment, new energy small equipment plastic structural frames

• Medical auxiliary equipment, environmental sanitation equipment ABS installation brackets

• Other large precision off-white plastic structural injection parts
