Supersonic alloy fusion injection + metallurgical bonding, ultra-abrasive, ultra-corrosion resistant, suitable for Ceramic processing and forming. Hardness: to obtain wear and corrosion resistance need to have sufficient surface hardness and thickness, and can cope with a variety of engineering plastics with fibre, fire retardants, flame retardants Ceramics, magnet powder and other special materials wear-resistant requirements of the corresponding hardness. Strength: Due to the use of Hitachi original high tenacity DAC-MAGIC is used as the base material, and the outer surface is covered with a 2mm alloy layer. The metallurgical bonding of the material results in a high flexural and compressive strength. ceramic porcelain screw finished product shipping inspection: finished product shipping inspection must be 12 hours soaked in concentrated sulphuric acid, no bubbles, no bubbles, no cracks, no corrosion, before packaging and shipping.
Scope of application: PA, PC, halogen-free materials added; PA, PC and other fibre added to 40% or Above; iron powder, ceramic powder and other raw materials that are easy to wear and pollution.
The materials are supplied by Japanese manufacturers Daido and Hitachi to ensure the authenticity of the raw materials. Machining process: The base material is machined to a round bar 1mm larger than the outer diameter of the product, quenched at a vacuum quenching temperature of 1020℃ for one hour, tempered at a high temperature of 500-530℃ and hardened to a hardness of HRC63, and then machined in a single operation by a CNC grinder. Advantages: low deformation, low internal stress, high precision and beautiful appearance. Suitable for: moulding of engineering plastics with up to 40% GF.
Scope of application: PC, PA, etc. with more than 40% fibre, bakelite, iron powder, ceramic powder, gold Diamond sand and high temperature, high voltage injection molding machine, etc.
