1. Extrusion part: To prevent the loss of energy and production resources, single-screw extruders or co-extruders are typically chosen for molding operations when producing profiles with small cross-section sizes, such as seals. The size of the product's section and the output requirement are the two primary considerations when selecting a single screw extruder. The section area of the profile is huge (the section size is large), and the screw diameter is larger when the extrusion yield is higher.
2. Extrusion mold: The primary component of product molding, the extrusion mold's function is to consistently and continuously convert the cylindrical melt supplied by the extruder into a well-plasticized shape that resembles the channel section and geometric size. The profile items with good performance are achieved after cooling and further procedures.
3. Cooling setting part: the cooling setting table has a stainless steel sink and a water circulation system. The cooling is a circulating water spray cooling system, and the setting table has a front and rear moving device as well as a left and right, high and low adjustment device.
4. Traction part: The traction machine is a form of frequency conversion speed regulator that continually and automatically leads out the cooled and hardened seal from the head.
5. Cutting collection part: By the stroke switch in accordance with the length control requirements, automatic cutting, and delay to push down; the implementation of water production; the cutting machine to fixed length switch signal as the instruction; the cutting process to keep pace with the profile operation; the 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.

Sealing strips made of PVC, TPU, and TPE are common and necessary. For example, sealing strips for windows, doors, refrigerators, electric cabinets, decorative strips, etc.
1. PVC sealing strips are easy to install by hand; they don't require heating or special tools, and the joint doesn't require hot melt glue or tape to strengthen the seal;
2. They are appropriate for a variety of cable connection seal specifications and can be used indoors, outdoors, overhead, underwater, or in other situations involving power and communication cables;
3. robust resilience, radial retraction force, minimal deformation, tight seal, moisture-proof, waterproof, and dust-proof performance, even after extended usage of the cable;
4. While PVC seal can still have a very strong sealing effect in the dynamic environment of wind blowing and swaying, EPDM may "breathe" with the seal due to its excellent resilience and "elastic memory";
5. Resistance to salt spray corrosion, resistance to acid and alkali, resistance to ozone aging, resistance to weather aging, and resistance to UV aging;
6. Excellent wear, flexure, fatigue, and puncture resistance, as well as strong mechanical strength and flexibility.
