Silicone Catheter Manufacturing Machine LSR Molding and Extrusion

Introduction

Silicone catheters are widely used in modern healthcare. An increasing number of people require high-quality silicone catheters for urinary drainage or post-surgical applications.

Manufacturers require efficient and reliable machinery that is specifically designed for producing silicone catheters. In this article, we will look at the two main types of equipment used for this purpose: LSR injection moulding machines and silicone extrusion lines. We will also explain how these machines work together to produce safe, precise and high-performance medical catheters.

Two key machines are used to make silicone catheters

To make high-quality silicone catheters, two types of equipment are usually used:

1. Liquid silicone rubber (LSR) injection moulding machine

This is the main machine used to make the catheter balloon and head section. One of the best models is TYM's 130-ton vertical double sliding LSR injection molding machine.

Key advantages

Dual lower molds with one upper mold, allowing simultaneous loading/unloading and molding, which significantly increases production efficiency.

Automation-ready, with support for blow-off demolding and robotic arm integration.

Ideal for high-precision medical parts such as silicone urinary catheters tips, valves, and balloon segments.

2. Silicone Tube Extrusion Line

Used for producing the flexible silicone urinary catheters tube body. Silicone extrusion machines provide consistent tubing diameters and wall thickness, ensuring the catheter's comfort and function during insertion.

Why Choose TYM for Silicone Catheter Manufacturing?

l Over 10 years of experience in medical-grade silicone processing

l Custom LSR solutions with CE and ISO certifications

l Global client support with full technical training and after-sales service

l Proven performance in catheter, nasal cannula, and urinary products manufacturing

Additional Production Steps

After molding and extrusion, a complete silicone catheter goes through several secondary processes:

l Punching for drainage holes

l Bonding the balloon to the tube

l Valve assembly and lubricant coating

l Sterilization and packaging in cleanroom environments

One Mold, Multiple Sizes

One standout feature of TYM's silicone catheter production solution is its multi-size compatible mold system. A single mold can support three adjacent silicone urinary catheters sizes by simply switching interchangeable inserts (up to 6 inserts in total). This significantly reduces mold investment costs and minimizes downtime when switching between sizes.

Conclusion

If you’re planning to manufacture silicone catheters at scale, a combination of LSR injection molding machines and silicone tube extrusion lines is the ideal solution. TYM's high-efficiency systems and modular tooling design make it easier for manufacturers to optimize costs, improve production speed, and maintain product consistency across different catheter models.
