PCS30 single-screw/single-rod extruder for laboratory use for powder coatings production line: Technology has been improved based on Switzerland BUSS kneader.
The lab use extruder is suitable for evaluation of color blending and raw materials, R&D of new formula, and pre-inspection of pre-mixing batch materials.

Traits of PCS30:
>> Desk-type design for space saving;
>> Able to reproduce product quality during the production process;
>> Production process accurate and reliable.
>> Use of original premixers, no pregrinding required.
>> Split barrel design for easy access to the process section.
>> Two independent heating/cooling zones, segmental screw, variable screw speed, choice of die diameters.

Degold produce a new lab use extruder with novel screw design: Each circle of the screw rod is sectioned into 3 washer, which keep reciprocating motion during the swiveling of the screw rod and change to seesaw motion when the rod finishes one circle of rotation. As a result, a fierce shear action is generated between the rotary screw thread and the 3rows of pins with 120° Angles which are mounted in the feeding container.
Frequency-converter screw reciprocating movement and adjustable shear force can optimize the mixing process as best. Materials can be cut, segment, kneadered, re-set, loose mixing in the shear clearance among screw sheet, screw corner and pin, to reach the excellent dispension and distribution result. Reciprocating shear continuous process make shorter time of working process, nallower distribution of materials, lower temperature of products and excellent cleansing ability for products.

Traits of PCS series extruder:
1. Compact design: Feeding unit, driving unit and heating/cooling unit are intergrated; Delivered to customers as pre-assembled pipes and wires, therefore can be installed within a short time.
2. Double-screw sideways feeding unit: Allowing higher feeding rate.
3. Modular machining unit: Can replace and recorganize screws according to the process requirements.
4. Improved dispersion: Screw rotation increased to 500r/min, allowing higher rate of dispersion and material flow.

Any questions and comments are great appreciated here all way.
