Does the plastic temperature that note model lead impact there is what to shortening?

Makings is lukewarm
Sticking shed temperature above, the connection of the viscosity of high polymer and temperature follows the accretion of temperature, the comfortable bulk of fuse-element can be added, the mutual effect force between the element can be weakened, can add the liquidity of high polymer, the viscosity of fuse-element can follow temperature to add the method with the index to drop, because model is noted in high polymer,want to progress in treatment the ability full a pattern of fuse-element, temperature is the principal technique that recuperates viscosity.

No matter be the mechanism respect of the crystallization from polymer and orientaton,bilge according to heat probably cold shrink does the principle think: ?

Can this kind of state explain for: ? Hold green press and smooth to chant Huan of Si of Yao Xi  to if give or take an injection at the moment,pull barefooteding? of Ran  cave pressure and dwell pressure hold to changeless, so the speed that runner freezes can be decelerated, adumbrative protect the hour that press outspread, fill the effect that shrink can increase, density also can progress accordingly, because this shortens,frank meeting drops.

By afore-mentioned analysing knowable makings is lukewarm the influence that shortens about shaping is crystallization shortens, orientaton shortens, heat shortens and preserve the gain that reduces short integrated effect, if in front 3 kinds of impacts that shorten are very big, finished product shows after all shorten the temperature that frank meeting follows fuse-element is added and increase; contrary, protect pressure fill shrink shorten when the effect is bigger rate temperature is added and will reduce accordingly.

Mould temperature
Thermoplastic after plastic fuse-element infuse antrum, the quantity of heat with very much acquit and condense, different plastic sort, demand model antrum is maintained in one proper temperature. Here temperature falls, will most be helpful for model shape, model shape power is supreme, internal stress and warpage are the smallest.

Mould temperature is to hold the chief factor that accuses finished product refrigeration to finalize the design, it shortens to shaping the effect of rate is first before expressing drawing of patterns of the finished product after runner freezes nowadays this paragraph of process. And before runner freezes, although have the tendency that increases shrink weak point,modular Wen Tian is added, but also be higher standard lukewarm make runner freezes hour is outspread, cause give or take an injection pressure and the influence that keep pressure increase, fill shrink the effect and negative shorten the quantity all can increase.
