During the production process of a silicone extruder, bubbles or pinholes may appear on the product surface, compromising product quality. What could be the underlying causes?

During the production process of silicone extruders, bubbles or pinholes may appear on the product surface, compromising product quality. This can be attributed to excessive moisture or volatile content in the raw materials, an inadequately designed or blocked venting system, improper temperature settings, excessively high screw speeds, or defects in the mold runner design.

Structural Composition of a Silicone Strip Extruder

In our daily lives, we often encounter silicone products such as silicone gloves, door and window seals, LED flexible light strips, automotive glass seals, and medical-grade silicone items. It’s safe to say that silicone products have become inseparable from our everyday routines. Most of these products are manufactured using silicone extruders—particularly silicone tubes, strips, and custom‑shaped profiles—because this method delivers high production efficiency, large output, and excellent quality. Silicone strip extruders are fundamental equipment in the silicone industry, playing a crucial role in tube‑making processes. Let’s take a closer look at the structural components of a silicone strip extruder. I. Process Structure of a Silicone Strip Extruder A typical silicone strip extruder consists of a drive motor, gearbox, speed regulator, feed hopper, extrusion screw, and extrusion die. II. Analysis of the Silicone Strip Extruder’s Operating Process 1. Preparations Before Starting the Machine (1) Inspect all machine components for abnormalities, check fasteners for looseness, and verify that there are no leaks in the piping system. (2) Fill the gearbox with filtered lubricating oil, ensuring the oil level matches the mark on the oil dipstick; also, apply sufficient grease to all lubrication points. (3) Prepare the necessary plates and various tools. (4) According to the instructions issued by the machine…

Introduction to the Extrusion Molding Process of Silicone Rubber Strips and Its Applications

The extrusion molding process of a silicone strip extruder is also highly complex. Taking the production of tires with a silicone extruder as an example, during tire manufacturing at relatively low temperatures, the extrusion method is used to melt the silicone material, which is then forced through the die opening of the extruder head to form the desired shape. This is a challenging process that requires not only a thorough pre‑operation inspection of the extruder but also operators with substantial experience. Only by combining technical expertise with practical know-how can this process be executed effectively. Next, let’s explore the extrusion molding process and applications of silicone strip extruders. The extrusion molding technique employed by silicone strip extruders has relatively high technical requirements; however, it offers greater efficiency and helps reduce production costs, making it well worth widespread adoption across the industry. During operation, it is crucial to ensure that the extruder applies adequate pressure to the feed inlet to maintain stable product output. Accordingly, appropriate temperature‑control measures must be implemented—cooling the mold temperature is an effective approach. Additionally, since the rubber extruded from the die has not yet undergone vulcanization, it remains relatively soft and must be further cured in a vulcanization oven. After being extruded, silicone products pass through a pre‑heating vulcanization tunnel, where they are suspended in the air to achieve preliminary vulcanization and rapid curing.
