PP/PE/PA6-produktionslinje til koldtryksplader – giver mulighed for opgradering af tykpladestøbning med lavtemperatur-koldtryksteknologi

As the plastic thick plate processing industry pursues low internal stress, high flatness and low material loss, the low-temperature cold push board extrusion process has become the preferred solution for solid bar/thick plate production, thanks to its advantages of low deformation, smooth surface and compatibility with various raw materials such as PP, PE and PA6 nylon. Relying on years of ekstruderingsstøbning technology innovation, JWELL deeply integrates single-screw low-temperature plasticization, tempering shaping, servo crawler traction and precision fixed-length cutting processes, realizing continuous and stable production of full-spec plastic bars from Φ5 to 300mm. Parameters such as traction speed and cutting length can be flexibly adjusted online, greatly reducing downtime loss and raw material waste caused by material and specification switching.

This material system has achieved full-scenario coverage spanning basic livelihood sectors to strategic emerging industries, playing an irreplaceable role in every link of industrial manufacturing and daily life.

High Efficiency Low-Temperature Extrusion System

The JWS50/28 special single-screw extruder is equipped with a custom screw structure for cold push process, which accurately controls low-temperature plasticization of PP/PE/PA6 to avoid yellowing of nylon caused by high-temperature degradation, delivering stable and uniform extrusion output.

Temperature Control and production capacity：Dual temperature control (4-zone ceramic heating 16kW + fan cooling), skrue i legeret stål (≥HV740) and honed barrel (≥HV940) in precision fit guarantee strict melting range control and reduce internal stress. Capacity 15-25kg/h for 650mm cold push board.

Precision Tempering & Shaping Process

Exclusive tempering plate with precision temperature control adapts to low-temperature shaping of PP/PE/PA6 thick boards for stable dimensions and high flatness.Setting plates: 700×850×70mm (45# steel) and 1700×850×70mm (aluminum), ~4-zone heating, matching ekstruder output; multi-cavity molds (16/12/10/6/4) support Φ5-300mm bars with traction speed adjustable in real time.

Closed-Loop Continuous Production: It fully realizes the continuous operation of the entire process of "extrusion → tempering shaping → traction → cutting".

Dual Crawler Servo Traction Conveying System

Clamping & Conveying: Developed for cold push thick boards.Independent upper/lower servo drives (Inovance 0.85kW each); flexible clamping by silicone wear-resistant blocks (steel-lined) prevents scratches. Pneumatic clamping with adjustable pressure (valve + gauge) suits various bar sizes for stable conveying.

Frame & Speed: Screw-lift frame; lower center height 1050mm, opening 150mm, compatible with Φ5-300mm bars. Max speed 60mm/min, dual control (touchscreen/cabinet), linked with cutter.

Hjælpefodringssystem

100kg hot air dryer ensures moisture content meets standard; 100kg/h vacuum loader enables automatic continuous feeding with reduced manual intervention. Integrated compact design with low energy consumption and noise for better workshop environment.

Precision Fixed-Length Cutting & Automatic Stacking Unit

Precision Cutting & Auto-Stacking: Servo encoder ensures cutting length error within ±1mm; VFD-controlled saw motor with screw-lift cutting table supports boards up to 150mm thick, with chip tray. Cut boards are auto-conveyed to integrated stacking rack, reducing manual handling, boosting automation and labor savings.
