Guidelines - Plastic Extrusion Process

Water Cooling
Using the water circulation to cool the extruded profiles,and thespeed of cooling determines the production speed of the product.This kind of cooling process is suitable for produce some simple PCdiffuser, Tri-proof light lampshade, because the capacity is very high,can reach a ton a day.The biggest disadvantage is that due to the fastextrusion speed,there will be puling lines on the product surface andthe product dimensions are not stable.

Embossing
Hot embossing process is using for irregular profile, which is differentfrom the cold embossing used by diffuser sheet. Extruded profile passthrough the roller after it comes out from the mold, the pattern on theroller is pressed on the product surface before profile is completelycooled, and then the surface embossing is formed by natural cooling.It is not difficult to make an embossed profile, what is difficult is to makea pattern that can achieve the purpose of controlling the optics, whichis the case with our micriprismatic lens.

Co-Extrusion
The plastic co-extrusion process involves extruding two or more together into a single structure before cooling.It is suitable for Tri-proof light lampshade, T5, T8 or Lens and materials through a single mold so that materials merge or weld diffuser need reflector.
