HOOHA Paste Extrusion Related Equipments


We have all machines for paste extrusion system.

Blender

Blender mixes raw PTFE powder and lubricant (naphtha) at the first step of paste extrusion process.

Our blender has a hollow cylinder (bottle holder) which has a plastic bottle inside. The cylinder rotates in two ways -- circumferential and axial direction. Usually the plastic bottle is made of polyethylene or PET. Rotation and time are adjustable. Because of this mechanism our blender does not cause particle shear, and it hardly grows small ball like lumps.

Before extruding, blended raw PTFE have to be pre-formed.
Pre-former forms blended PTFE powder into a clolumn or a cylinder with certain pressure.

Maxmum length of formed material is 1000mm (approx. 40 inches).

Oven for drying and sintering

Extruded PTFE still has lubricant and is soft an fragile. Therefore it must be sinterd in the next step. Sintering temperature is 100 to 500 degree Centigrade.
Our drying and sintering oven has a stable heat control system.

Length of the oven is 4 to 20m.
