Custom Gasket Cutting: Waterjet, Die Cut & CNC (Comparison & Best Uses)

Gasketech specialises in custom gasket cutting in Melbourne using waterjet, die cut, and CNC methods for precise sealing solutions for every industry.

Precision manufacturing relies on accurate, efficient, and material-appropriate gasket cutting techniques. We at Gasketech offer a range of cutting solutions tailored to meet performance, tolerance, and production requirements. Understanding how each method—waterjet, die cut, and CNC—functions ensures clients receive gaskets that match demanding industrial standards.

Waterjet Gasket Cutting for Complex and Thick Materials

Waterjet cutting is a precise and versatile custom gasket cutting method that uses a high-pressure stream of water mixed with abrasives to shape materials accurately. The process eliminates heat-affected zones, maintaining the integrity of rubber, graphite, PTFE, and reinforced composites. It delivers exceptional edge quality and eliminates the risk of distortion or hardening caused by thermal cutting methods.

This technique excels at cutting multiple layers and dense materials up to several inches thick, making it ideal for complex geometries. Waterjet technology provides consistent results for low to medium-volume production runs and prototype development. It ensures precise tolerances, clean finishes, and repeatable accuracy, essential factors in high-performance custom gasket cutting applications.

Die Cut Gaskets for High-Volume Production

Die cutting is a cost-effective custom gasket cutting technique widely used for high-volume manufacturing. It employs precision steel-rule or solid dies to stamp material sheets into uniform shapes quickly and consistently. Once tooling is developed, the process delivers exceptional production speed and repeatable accuracy across large quantities.

This method ensures tight dimensional control and compatibility with a broad range of non-metallic materials, including rubber, cork, and fibre. Die cutting is most effective when tooling costs can be offset through extended production runs. It remains the preferred solution for consistent, large-scale custom gasket cutting applications that require efficiency and reliability.

CNC Knife Cutting for Precision and Flexibility

CNC knife cutting offers digital accuracy and flexibility for gasket production that requires quick turnaround and design adjustments. This computer-controlled process operates without water or dies, making it suitable for sensitive materials and one-off jobs.

Technical benefits include:

•  CAD-Driven Accuracy: CNC knife cutting integrates directly with CAD software, allowing rapid design adjustments and precise gasket replication.

•  No Tooling Costs: The process eliminates the need for physical dies, reducing setup time and production expenses for custom gasket cutting.

•  Material Versatility: Suitable for soft, layered, and sensitive materials that cannot tolerate heat or pressure from other cutting methods.

•  Consistent Edge Quality: Delivers smooth, burr-free cuts with repeatable accuracy ideal for prototypes and small production batches.

•  Efficient Turnaround: Enables quick lead times for urgent orders or product development, ensuring reliable performance in dynamic manufacturing environments.

Choosing the Right Gasket Cutting Method

Selecting among waterjet, die cut & CNC depends on several factors:

•  Material composition: Dense or multilayer materials favour waterjet cutting.
•  Volume requirements: Die cutting is the most cost-effective for large-scale production.
•  Design complexity: CNC cutting excels in producing custom or prototype designs.
•  Tolerance and edge finish: Waterjet and CNC maintain tighter tolerances than die cutting.

Each technique offers specific strengths in terms of accuracy, efficiency, and cost, allowing us to provide tailored gasket cutting solutions that meet project specifications and budget constraints.
