Jiaxing bearing | I tidy up the mold injection molding processing method, can you see?

There is rotational, have HRB bearing ( ) Jiaxing bearing | I tidy up the mold injection molding processing method, can you see? Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. When injection mold processing, are generally formed by batch, so we to the mold injection mechanic method and process is very seriously, if at the time of processing, not according to the requirement of the regulations, will damage the injection mold. Therefore, jiaxing bearing the author introduce mold injection molding process analysis processing method for everybody: 1, generally do not need to dry raw materials, individual condition of 80 ℃ baking 2 hours; 2, molding temperature range is larger, heating and curing speed, melting, molding cycle general short; Temperature parameters: the cylinder temperature about 200 ℃, the material temperature too high susceptible to silver, the material temperature is too low will make poor transparency; 3, mold temperature control: mould temperature is in commonly 50 - 80℃； 4, GPPS liquidity is very good, does not require high pressure in the plastic beer ( Usually injection pressure around 10 mpa) The increasing rubber pieces of internal stress, in order to avoid too much can lead to cracking ( Especially after the paint decoration process) ； 5, high injection speed appropriate to decrease water lines, but due to the injection speed is influenced by the injection pressure is big, high speed may lead to put front or sticky mold and the mold ejection when top white tip crack problems; 6, the appropriate back pressure: if low back pressure, screw rotation is easy to spill into the air, within the cylinder material density is small, colloidal particle plasticizing effect is not good, glue pieces of apparent quality, Take 10 - general back pressure 20kg/cm2) ; g） Die nozzle on the general design of thin to 0. 8 - 1. 0mm. h) PS - glass fiber reinforced type GF30, cylinder temperature is 180 ~ 275, mold temperature is 20 ~ 80, molding shrinkage of 0. 1 to 0. 2. Density of 1. 29/cm3。 If you are looking for the above jiaxing bearing group co. , LTD.
