A:Answer: Degreasing, rust removal, primer spraying, and anti-rust paint spraying.
A:A: Surface roughness Ra6.3, tolerance: ±0.05
A:A: CNC machining has better precision than wire EDM. You can request CNC machining when placing an order. We are also gradually reducing the number of molds that require wire EDM.
A:A: CNC can machine inner cavities larger than R4 (inclusive) and smaller than 80mm (inclusive). CNC can machine arc corners or sharp corners smaller than R4. CNC is approximately 50%-70% faster, depending on the brick sample and quantity. CNC is more expensive, and the price is calculated based on the brick sample and quantity.
A:A: Welded molds have shorter lead times, and the process is more mature. Prefabricated molds have longer lead times. We have only produced a few sets so far, and the process is still under development. However, this also requires the customer to have certain assembly capabilities on-site.
A:A: Full welds provide better connection strength but are less prone to deformation. Segment welds provide less connection strength than full welds, but are less prone to deformation. We choose full welds or segment welds based on the mold's intended location. We use full welds for the base plate and mold frame, and segment welds for all other locations.
