Brief introduction of powder metallurgy process and products:
Powder metallurgy products are made of metal powder, such as: iron powder, copper powder, stainless steel powder, etc., which are refined by forming-sintering method. The traditional process: powder mixing-pressing-sintering-finishing-post-processing (oil immersion ; packaging; machining, etc.). That is, firstly, the prepared high-purity mixed powder is placed in the mold, pressed under a certain pressure, and then the compact is sintered in a controlled atmosphere sintering furnace at a temperature lower than the melting point of the base material to make the powder particles form a metallurgical bond.
Processing flow of powder metallurgy smart lock accessories:
Processing route of powder metallurgy stainless steel parts:
Raw material mixing→shaping→degreasing→sintering→subsequent treatment
Mixing: Stainless steel powder, additives, etc. were mixed and stirred for 1 hour.
Forming: According to the size, structure and shape of the product, design the mold drawing, make the cemented carbide mold according to the drawing, then install the machine and test the mold, and press out the sample. The mold design and production cycle takes one week.
Degreasing: Degreasing at a temperature of 800 degrees in a vacuum bell furnace or a mesh belt furnace to remove the added lubricant, cycle: 8-10 hours.
Sintering: temperature: 1250-1350 degrees, cycle 12 hours.
Subsequent treatment: polishing, oil immersion, heat treatment, machining, etc.
Processing route map of iron-based powder metallurgy parts:
Raw material mixing→shaping→sintering→subsequent processing
Raw material mixing: atomized iron powder, electrolytic copper powder, nickel powder, molybdenum powder, cobalt powder, ferrophosphorus powder, iron chromium gold powder, manganese sulfide powder, graphite powder, wax powder, powder mixing time 2 hours.
Forming: According to the size and shape of the product, design the mold drawing, make the cemented carbide mold according to the drawing, then install the machine and test the mold, and press out the sample. The mold design and production cycle takes one week.
Sintering: The temperature is 450°C-1150°C, 450°C is the rapid dewaxing zone, 1150°C is the sintering zone, and the cycle is 4 hours.
Subsequent processing: According to the different requirements of parts, the route of subsequent processing is different. The specific ones are as follows: oil immersion, polishing, machining, heat treatment, electroplating, finishing, repressing and refiring.
Powdered iron-based and copper-based products, because the product itself has a special oil-containing function of powder, so that the product has its own anti-rust aid function, which effectively prolongs the product life. According to customer requirements, powdered iron-based products undergo post-processing, such as blackening, polishing, Electroplating, fine grinding, etc., so that the product can prevent rust, slow oxidation, and beautify the appearance. It makes the product have wear resistance, rust resistance, natural corrosion resistance, etc. Due to product objections, it is suitable for small metal locks Component.
