Its unique design and advanced feeding system enhance production stability while reducing reliance on manual labor. The high compression ratio and long length-to-diameter ratio of the screw improve extrusion density and mixing performance, resulting in products with smooth inner and outer surfaces, no air bubbles, and consistent dimensional stability. Key Performance Features of the Silicone Strip Extruder 1. Equipped with an AC motor and variable-frequency drive, this machine offers a wide speed range, enabling flexible adaptation to produce silicone rubber products of different specifications, with convenient operation. 2. It utilizes a specialized hard-toothed gear reducer designed specifically for rubber extruders, providing low noise, high transmission torque, reliable and smooth operation, and easy maintenance. 3. Featuring pneumatic forced feeding, the machine can process multi-layer rubber strips, ensuring dense extrusion and superior product quality. 4. A dual-channel automatic temperature controller is incorporated, minimizing temperature fluctuations during heating. This allows for optimal selection of heating temperatures based on specific processing requirements and enables automatic control of set temperatures for both the barrel and die. 5. The machine employs electric heating for the barrel combined with circulating cooling, providing immediate and reliable cooling to prevent material degradation. Operation and Maintenance Guidelines for Silicone Strip Equipment 1. Before use, fill the hard-toothed gear reducer with appropriate lubricant—gear oil in summer and No. 45 mechanical oil in winter—and replace it regularly to extend the gearbox’s service life. 2. Prior to starting the silicone strip extruder, inspect the power supply to prevent motor damage or burnout caused by poor electrical contact. 3. Before operating the vacuum die head, tighten all screws and fasteners; after shutdown, thoroughly clean out any remaining material. Once started, adjust the core properly. 4. Before use, check whether metal fragments have entered the barrel and screw to avoid potential damage. Before stopping, ensure all material has been completely extruded from the barrel and screw to prevent residual cured material from affecting subsequent operations. 5. (1) Clean the gearbox oil tank and verify that gear meshing shows no signs of wear. Adjust the belt tension appropriately and periodically add wheel lubricant. (2) Remove any cured material from the barrel and screw interior to prevent leakage and ensure unobstructed water flow within the machine’s water jacket. (3) Regularly inspect the vulcanization chamber for bearing and rotating shaft wear or looseness, determining if component replacement is necessary. Also, check the heating and sealing systems for required repairs or additions, such as replacement of heating elements, and clean ventilation ducts to maintain proper rotation.

Purpose

It is suitable for the efficient extrusion and continuous, rapid vulcanization of various silicone‑based profiles, including silicone strips. The unique design of the silicone extruder, coupled with its advanced feeding system, enhances production stability and reduces reliance on manual labor. A high compression ratio and a high length‑to‑diameter screw configuration further improve extrudate density and mixing uniformity, resulting in products with smooth inner and outer surfaces, no bubbles, and consistent dimensional stability.

Performance Characteristics of Silicone Strip Extruders

1. This machine is equipped with an AC motor and a variable-frequency drive, offering a wide speed-regulation range, excellent adaptability to the production of silicone rubber products in various specifications, and convenient operation.

2. This machine is equipped with a dedicated reducer for hard-tooth-surface rubber extruders, featuring low noise, high transmission torque, reliable and smooth operation, and convenient maintenance.

3. This machine employs pneumatic cylinder‑driven forced feeding, enabling the processing of multi‑layer rubber strips with dense extrusion and superior product quality.

4. This machine is equipped with a dual-channel automatic temperature controller, ensuring minimal temperature fluctuations during heating. It allows for optimal selection of the heating temperature based on different processing requirements and automatically maintains the set temperatures of the heated barrel and die head.

5. This machine employs electric heating for the barrel and a circulating cooling system, enabling rapid and reliable cooling of the material to prevent thermal degradation.

Silicone Strip Equipment Operation and Maintenance

1. Before use, the hardened‑tooth‑surface reducer must be filled with lubricant (refer to the oil dipstick): use gear oil in summer and No. 45 mechanical oil in winter. Regular oil changes will help extend the reducer’s service life.

2. Before starting the silicone strip extruder, check the power supply to prevent motor damage or burnout caused by poor electrical contact.

3. Before using the vacuum head, tighten all screws and fasteners; after shutdown, thoroughly clean out any adhesive. Once the machine is started, adjust the core to ensure proper alignment.

Before use, check whether any iron particles have entered the silicone rubber in the barrel and screw to prevent damage. Prior to shutdown, ensure that all material has been completely extruded from the barrel and screw to avoid cured material affecting subsequent operations.

5(1) Clean the transmission oil tank, inspect the gear meshing for wear, adjust the belt tension to an appropriate level, and lubricate the wheels with wheel grease at regular intervals.

(2) Clean the material cylinder, screw, and inner cavity of any cured material; otherwise, glue leakage may occur. Ensure that the water in the machine’s water jacket remains unobstructed and clean.

(3) Regularly inspect the sulfurization chamber to assess wear and looseness of bearings and rotating shafts, and determine whether any components need to be replaced. Also, check the heating and sealing systems; if necessary, replace or add heating elements, and clean the air ducts to ensure smooth rotation.
