Step 1: mix and to get the raw materials ready, with Fe powder, Ni powder, Co powder Fe powder 54% by weight percentage, the Ni powder: 29%, Co powder 17% is sent in the V-type batch mixer, fully mixes.
Step 2: the preparation feeding, at first 70: 30 by weight percentage mixed of paraffin and polyethylene is become binding agent, step 1 gained mixture and 89: 11 by weight percentage ratio of binding agent are sent in the high mixer the mixed product feeding that gets.
Step 3: moulding, use injection machine that above-mentioned gained feeding is expelled in the mould, be under 150 ℃-170 ℃ the condition, to make the product blank, and pare off cast gate and overlap at forming temperature.
Step 4: extraction, the gained blank is put into extractant alcohol, extraction is 12-48 hour under temperature 60-80 ℃ condition, and the wax in the blank is extracted.
Step 5: degreasing, the blank after the extraction is put into debinding furnace, under the condition of 450 ℃-600 ℃ of temperature, degreasing 30 hours removes binding agent remaining in the blank.
Step 6: sintering, the blank after the ungrease treatment is sent into sintering furnace, sintering is 30 hours under the condition of 1200 ℃-1300 ℃ of temperature, obtains sintered part.
Step 7: polishing, the sintered part that obtains is put into polishing machine carry out polishing, make product.
The present invention adopts the powder metallurgy injection molding technology in manufacturing process, stock utilization is increased to 100% from about 50%, and product density reaches 7.9g/cm
3, compare with traditional processing technology, have and can effectively reduce production cost, enhance productivity and significant advantage such as product size precision.
