Because of its vaiety, the melting tematue is within the ange of 300~425 C. The viscosity of LCP melt is low, the fluidity is good, and it is simila to the olefin pltic. LCP h a vey small coefficient of linea expansion and a good dimensional stability. The foming pocessing conditions ae follows: molding tematue 300~390 C, mould tematue 100~260 C, molding pessue 7~100MPa, compession atio 2.5~4, and molding shinkage ate 0.1~0.6.1. bael tematueeally, the tematue of the bael, the tematue of the nozzle and the melting tematue of the mateial ae shown shown in the table.If the sevice life of the scew is taken into account, the tematue diffeence between the ea, the middle and the font can be educed. In ode to pevent the nozzle salivation, nozzle tematue than shown in the table of the low tematue of 10 DEG C, if you want to impove the liquidity, the tematue can be shown in the table than the tematue highe than 20 DEG C, but must pay attention to the following cicumstances.When the bael tematue is loweed, the detention time is too long, which will not cause the aging of ganula mateial in the containe and no coosive g. Theefoe, thee will be no big poblems if the esidence time is long. Howeve, if the molding is inteupted fo a long time, plee educe the tematue of the bael. When it is e fomed, it is good to thow out a few models.Bael tematue (centigade) fo each gade moldingPA6 PA6, also known nylon 6, is a tanslucent o opaque milky white paticle.

The unne and gate: because PA612 solidification time is vey shot, the gate location is impotant. The atue not less than 0.5*t (whee t is the thickness of pltic pats).
