Castor product structure

1 caster and product structure. Castor how simple, but also have complicated, need 7 sets of hardware mold to fix, complex shape, the concave, mould price is 50 w, this kind of situation is relatively rare in the castor, but in the PROE bending or the trouble; Plastic more complex, modeling, smoke shells are demanding. 2. Structure. Castor is big more, less precise size, the connecting way generally for riveting, welding, lock screw, also have interlocking, plastic on them more for decoration, such as stainless steel smoke lampblack machine, consider heat dissipation, electromagnetic radiation, noise, the plastic deformation, rodents and grounding problem; More for small pieces of plastic, size precision, the connecting way generally for buckle, ultrasound, lock screw, castor on them more for decoration, like mobile phones, sometimes will consider waterproof, dust-proof, antistatic, anti electromagnetic radiation, have the horn and the problem of sound cavity before and after, xiao called question 3. Surface treatment. Castor is commonly on the surface of wire drawing, polishing, sandblasting, anodic oxidation, electroplating, electrophoresis, screen printing, oil spraying, laser carving, castor and anti-rust, anti-static and conductive problem; General pieces of plastic for injection, silk screen, bronzing, electroplating, Water plating, vacuum plating) , water transfer printing, IMD, drawing after electroplating, UV, PU, electroforming, laser carving, double color 4. Castor for general stamping forming way, stretching, bending, flanging, die casting, precision casting, the profile is commonly pieces of plastic injection molding, blow molding 5. Prevent castor with mold and defects in general with model is relatively simple, product defects are mainly concentrated in die casting. Caster, caster wheel factory, Shanghai universal wheel, universal casters
