Hot Gas & Extrusion Welding

Custom Hot Gas and Extrusion Welding Services – Reliable Plastic Welding for Complex Assemblies

At Poly Synthesis, we specialise in hot gas and extrusion welding services for plastic fabrication projects that demand high precision, strength, and durability. These advanced welding techniques are ideal for joining thermoplastic materials in large-scale projects and complex assemblies where seamless, leak-proof bonds are critical. Our custom hot gas and extrusion welding solutions are tailored to the specific requirements of industries ranging from chemical processing to water management and heavy industrial manufacturing.

Hot gas welding is perfect for small, intricate welds, while extrusion welding is designed for larger joints and thicker materials. By utilising both methods, we ensure that your plastic components are joined with maximum strength and reliability, delivering a long-lasting solution that performs under pressure, in tough environments, and under the most demanding conditions.

Whether you’re working with large storage tanks, complex piping systems, or industrial enclosures, our expertise in hot gas and extrusion welding ensures that your project benefits from strong, secure joints that meet the highest standards of performance and safety.

Delivering Superior Welding for Plastic Components of All Sizes

At Poly Synthesis, we understand that different plastic fabrication projects require different welding methods to achieve the best results. Our hot gas welding process is perfect for smaller, detailed joints, while extrusion welding is ideal for large-scale fabrications where thicker materials need to be securely joined. These complementary techniques allow us to create high-integrity, seamless joints for plastic sheets, pipes, and other components, ensuring leak-proof performance and structural integrity.

We specialise in providing custom plastic welding solutions that are tailored to your project’s unique requirements. From fabricating large chemical storage tanks to welding intricate plastic piping systems, our advanced welding services deliver strong, long-lasting bonds that keep your systems secure and operational.

Why Choose Our Custom Hot Gas and Extrusion Welding Services?

Choosing Poly Synthesis for your hot gas and extrusion welding needs ensures that you are partnering with a team dedicated to precision, quality, and superior performance. Here are four key reasons why our customers trust us with their plastic welding projects:

1. Expertise in Advanced Welding Techniques

We are experts in both hot gas and extrusion welding techniques, ensuring that your plastic components are welded with precision and strength.

  • Hot Gas Welding: This technique involves heating a filler rod with hot gas to join plastic materials. It’s ideal for small, intricate welds that require a high degree of precision. Commonly used for thin materials, this process ensures a smooth, consistent bond without compromising the structural integrity of the components.

  • Extrusion Welding: For larger-scale projects involving thicker materials, extrusion welding is the preferred method. This technique involves heating plastic and extruding it into a joint to create a strong, durable weld that can handle heavy loads and high-pressure environments. Extrusion welding is ideal for joining large plastic sheets, fabricating custom tanks, or reinforcing seams on industrial piping systems.

Our team’s expertise in both of these welding techniques allows us to select the best method for your project, ensuring that your welded components meet the highest standards of strength and reliability.

2. High-Integrity Welds for Leak-Proof Performance

Both hot gas and extrusion welding techniques are designed to create seamless, high-integrity welds that ensure leak-proof performance. This is particularly important for applications such as fluid containment, chemical storage, and industrial piping systems where the risk of leaks can lead to costly downtime or environmental damage.

Our precision welding techniques ensure that every joint is perfectly aligned and free from defects, providing you with a reliable, long-lasting solution that meets the demands of your industry. We take extra care to ensure that the welds are durable, robust, and resistant to the stresses that plastic components often face in harsh industrial environments.

Case Study: Custom Extrusion Welding for a Large-Scale Chemical Storage Tank

Client: A mining operation in Western Australia
Project: Fabrication and welding of a custom chemical storage tank for corrosive materials

Challenge:

The client needed a large, custom-fabricated chemical storage tank capable of withstanding exposure to highly corrosive substances. The tank needed to be leak-proof and able to handle heavy loads while remaining structurally sound over the long term in a remote mining environment. Due to the size of the tank, extrusion welding was required to create strong, seamless joints that would maintain their integrity under pressure.

various sample hdpe tanks

Solution:

We fabricated the tank using HDPE, chosen for its excellent chemical resistance and durability. Our team utilised extrusion welding to create strong, seamless joints along the tank’s large panels, ensuring leak-proof performance and structural integrity. To further reinforce the tank, we welded custom brackets and supports using hot gas welding, providing additional stability for the harsh mining environment.

Chemical Containment Tanks

Result:

The custom-fabricated chemical storage tank provided the client with a durable, leak-proof solution for handling corrosive materials. The extrusion-welded joints maintained their strength under pressure, while the hot gas-welded brackets ensured long-term stability in the challenging conditions of a remote mining site. The client reported improved efficiency in their chemical handling operations and reduced maintenance costs.
