The machine is used for producing sealing strip of PVC, TPU, TPE etc material, features hiah output, steady extrusion, low power consuption. Adapting famous inverter, SIEMENS PLC and screen, easy operation and maintenance.
(1) Extrusion part: For the production of profiles with small cross-section size such as seals, single-screw extruders or co-extruders are generally selected for molding processing to avoid the waste of production resources and energy. The choice of single screw extruder depends on two main factors: one is the size of the section of the product; The second is the output requirement. The larger the extrusion yield, the larger the screw diameter; The section area of the profile is large (the section size is large), and the diameter of the screw is larger.
(2) Extrusion mold: extrusion mold is the main part of product molding, its role is to continuously and uniformly transform the cylindrical melt provided by the extruder into a well-plasticized shape similar to the channel section and geometric size. After cooling and other processes, the profile products with good performance are obtained.
(3) Cooling setting part: the cooling setting table is equipped with a sink and a water circulation system, the sink is made of stainless steel, the cooling is a circulating water spray cooling, and the setting table is equipped with a front and back moving device and a left and right, high and low adjustment device.
(4) Traction part: The traction machine is used to continuously and automatically lead out the cooled and hardened seal from the head, which is a frequency conversion speed regulation type.
(5) Cutting collection part: By the stroke switch according to the requirements of the length control, automatic cutting, and delay to push down, the implementation of water production, cutting machine to fixed length switch signal as the instruction, complete the cutting process, in the cutting process to keep pace with the profile operation, cutting process by electric and pneumatic drive to complete, the cutting machine is equipped with dust suction device, the cutting generated debris in time, and recycling.

PVC, TPU, TPE sealing strips are widely used and essential. Such as window glass sealing strip, door sealing strip, decorative strip, refrigerator sealing strip, electric cabinet sealing strip, etc.
1, PVC sealing strip installation is simple, only manual operation, no heating or use of special tools, the joint does not need hot melt glue or tape to strengthen the seal;
2, suitable for a wide range of different specifications of cable connection seal, can be used in indoor, outdoor, overhead, into the water or buried and other occasions of power, communication cables;
3, resilience strong, radial retraction force, small deformation, PVC seal even if long-term use of the cable still maintains a permanent radial pressure, tight seal, moisture-proof, waterproof, dust-proof performance;
4, because EPDM has excellent resilience and "elastic memory", it can "breathe" with the seal, so it can play an excellent sealing effect, PVC seal can still maintain a very good sealing effect in the dynamic environment of wind blowing and swaying;
5, salt spray corrosion resistance, acid and alkali resistance, ozone aging resistance, weather aging resistance, UV aging resistance;
6, high mechanical strength, good flexibility, with excellent puncture resistance, wear resistance, flexure resistance, fatigue resistance of physical and mechanical properties.
Jwell started manufacturing screws and barrels in 1978, making it one of the earliest screw and barrel manufacturers in China. Its brand, "Jinhailuo", has become well recognized in the industry. In 1997, Jwell was established to begin the production of extrusion machinery. Today, Jwell is the vice president unit of the China Plastics Machinery Industry Association and one of the technology leaders in the extrusion machinery industry.
