The PRO-EASY Screw Dismantling Machine is developed to simplify the disassembly process of extrusion screw components during maintenance, repair, and material changeover operations. Its patented universal clamping structure allows operators to handle a wide range of screw element sizes without replacing complicated fixtures, helping improve maintenance flexibility and reduce setup time.
The hydraulic control system provides stable clamping and adjustable dismantling force, allowing screw elements to be removed safely while minimizing the risk of shaft deformation or surface damage. An aluminum alloy collet structure further protects critical components during operation, especially when handling high-value screws used in engineering plastics, masterbatch, pigments, and specialty compounding applications.
To improve workshop efficiency, the machine is also equipped with an auxiliary dismantling unit and support frame, making it easier to process extra-long or heavily bonded screw assemblies. Compared with traditional manual dismantling methods, PRO-EASY helps reduce labor intensity, shorten maintenance downtime, and improve overall operational safety in extrusion production environments.
Screw element diameter range: Ø30–Ø150mm.
Clamping pressure and disassembly pressure adjustable via hydraulic system; aluminum alloy collet provides effective protection for shafts and screws.
Equipped with an auxiliary disassembly unit to effectively solve difficult disassembly issues.
Efficient and safe operation, significantly reducing disassembly labor intensity and protecting operators.
Equipped with an auxiliary support frame to facilitate the disassembly of extra-long and overweight shafts.
Install the grippers that match the screw type on the hydraulic chuck (Grippers can be customized according to the screw type)
The hydraulic chuck clamps the screw by the control panel.
Fix the disassembly gripper, (as shown in the figure) the block pin is around the middle of the screw to be disassembled, if the screw is relatively short, use the next screw to push out the shorter one.

Pro Easy adopts precise control of screw heating before the process of dismantling.
The outer diameter of the screw is equal to the inner diameter of the heating coil minus 20mm to 40mm,(OD of SE=ID of heating coil – 20mm) and the coil specification can be customized according to the customer's screw model.
Insert the semicircular ferrule, use the clamp rod to remove the screw element from the clamp (as shown in the figure), tap to adjust the screw, move right (in the slow gear state), when the adjacent screw element becomes loose , long press to move screw rightward until the end of the stroke;
Use the extension sleeve and the screw disassembly Gripper to push the screw element out.

The disassembled screw elements and shaft must be placed by the operator according to the regulations, for example, they must be placed on a wooden pallet, and the next step can only be performed after the temperature drops.
Founded in 2015, Lemix is a professional manufacturer focusing on R&D, production and service of extrusion equipment. since 2026 year, we have two factories which covers an area around 10,000 square meters.
Our core business covers twin-screw extruders, hot-melt extruders, screw cleaning & disassembly machines, cooling system cleaners and barrel wear detectors. We also supply key spare parts including screw elements, barrels, shafts and gearboxes, together with full maintenance, repair and upgrade services. in addition, we import high-performance stainless steel and provide customized material solutions for barrels and screws, especially high-wear and corrosion-resistant Hastelloy alloys.
