H.D.Plastics is a premier plastic extruded company with the capability of Single and Coextrusion upon customer requests.
The most common resins are
- High impact polystyrene
Profile Extrusion including below types
Coextrusion Profile—Rigid and Flexible
Vinyl Siding profiles
Various large and small profile shapes are replaced with an on-demand rotary cutter; as with the calibration and sizing tank, the cutter required depends on the profile size and the material.
Rigid PVC is used to make parts for building and construction markets such as :
- Window profiles
- Vinyl siding
- Fence posts
- Plastic lumber
PVC profiles are commonly operated on counter-rotating twin-screw extruders and particularly conical extruders, where PVC powder can be compounded with the required plasticizer concentration, lubricants, thermal stabilizers, fillers, and colorants to produce a commercial profile in one extrusion operation.
A profile production line consists of an extruder, cooling tank, puller, movable saw to cut the product, and product packaging. The cooling tank can be a vacuum calibration tank or a cooling tank without vacuum, depending on the profile being produced. Our H.D.Plastics own 10 sets of extrusion lines with twin-screw extruders for high tough PVC extrusion manufacturing.
