Material Selection Adapts to Product Batch Requirements

2025-10-16

The material of blister molds should be classified according to production volume: for small-batch trial production, gypsum molds can be selected (production cycle 1-2 days, cost only 1/10 of that of metal molds); for medium-batch production, copper-plated molds are recommended (surface accuracy Ra ≤ 0.2μm, capable of withstanding 50,000 moldings); for large-batch mass production, aluminum alloy molds are used, combined with hard anodizing treatment, with a service life of up to 500,000 moldings. Matching mold selection with production volume can reduce the comprehensive cost by 20-30%.

Impurity Removal Before Electroplating Improves Surface Adhesion

The peeling of the electroplating layer on zinc die-cast products is mostly caused by the surface oxide layer and impurities. The standard process is: first, remove the oxide layer by pickling with 10% dilute sulfuric acid for 30 seconds, then treat with an ultrasonic cleaner (frequency 40kHz) combined with a neutral degreaser for 5 minutes, and finally enhance the surface activity through electrolytic activation (current density 2A/dm²). After treatment, the surface roughness of the product is Ra ≤ 0.8μm, and the adhesion of the electroplating layer can pass the 1mm cross-cut test without peeling.

Low-Temperature Three-Proof Process Balances Protection and Hand Feel

Traditional high-temperature waterproof treatment tends to make leather hard, so low-temperature solutions have become a trend. Using Texnology®FCB058 fluorine-containing waterproofing agent, after 5 minutes of immersion and dehydration, baking at 120°C for 3.5 minutes can achieve three effects of waterproofing, oil-proofing, and stain-proofing at the same time. This process makes the static water pressure value of leather reach over 1000mmH₂O, and the elongation at break remains above 30%, balancing protective performance and soft hand feel.
