PCS30 single-screw/single-rod extruder for laboratory use for powder coatings production line: Technology is accordance with Swiss BUSS kneader. 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 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° Angle which are mounted in the feeding container. To satisfy customers' growing requirements on powder coating production. Degold developed the enhanced version PCS--11D extruders, which are with stronger and higher effective during process of extruding than the previous 8D version. Traits of PCS series extruder: 1. Compact design: Feeding unit, driveing 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. Traits of PCS-11D version, desides previous 8D version: 1. Outpput increase under standard formulation. 2. Processing ability improvment for more demanding powder coating system with low viscosity and low filler cotent or under PT910 and Primid formulation. 3. High performance-price ratio. 4. Screw speed increased to 500-650r/min. 5. Process length extension 11L/D.
