Silicone rubber extrusion equipment typically consists of a silicone rubber extruder and a hot‑air vulcanization unit. Generally, a single‑color extruder produces only one shade; however, when the number of machines is insufficient to dedicate separate units to different colors, the extruder must be cleaned before switching production. One approach is to repeatedly extrude with rubber matching the desired color until the color stabilizes, at which point production can proceed; the cleaned rubber can then be blended into a black compound for further extrusion. Alternatively, the barrel and screw can be disassembled for thorough cleaning, after which they are reinstalled and production resumed. In contrast, a hot‑air vulcanization chamber avoids this complexity: the product is conveyed on a belt, minimizing friction‑induced discoloration during vulcanization.

Silicone rubber extruders are increasingly widely used in our daily lives. Cleaning and maintenance are crucial for these machines, so it’s essential to perform regular cleaning. If you’re interested in purchasing this type of equipment, please contact our company to place your order—our products and after-sales service are both backed by reliable guarantees.

Purpose

It is suitable for the efficient extrusion and continuous production of various profiled silicone products, including silicone strips. The specially designed silicone extruder, coupled with an advanced feeding system, enhances production stability and reduces operator workload. A screw with a high compression ratio and a high length-to-diameter ratio improves extrudate density and mixing performance, resulting in products with smooth inner and outer surfaces, no bubbles, and consistent dimensional stability.

Advantages of the Hebei Shuangda Silicone Extruder:

1. We can provide on-site trial runs and sample production according to customer requirements; if it is inconvenient to visit the site, we can send video footage of the equipment in operation along with sample results for the customer’s review.

2. We can offer custom non‑standard single‑color or two‑color extrusion solutions tailored to your specific needs. Additionally, we provide dual‑extrusion options to boost production capacity and efficiency, yielding products with excellent toughness and an attractive appearance.

3. You can choose extruded light strips or opt for custom‑made products, such as silicone tubes, silicone wires, silicone strips, sealing rings, and other similar items.

4. Short lead times, fast shipping—once the equipment arrives at the customer’s site, with one‑on‑one training, operators can immediately begin production.

5. Equipped with branded components, it features low noise, excellent performance, a low failure rate, and a long service life of up to 8–9 years.

Features of the Hebei Shuangda Silicone Strip Extruder:

1. The silicone raw material is of high quality and is classified as food-grade liquid silicone.

2. It exhibits excellent water resistance, resists yellowing, is impervious to water erosion, and maintains secure adhesion even when continuously illuminated underwater.

3. After sealing, it can maintain a color temperature that is close to the original, with minimal color temperature drift.

4. Superior silicone strength ensures long-term performance even in harsh environments, with excellent resistance to mechanical damage.
