Understanding Material Converting: From Raw Material to Finished Component

Imagine you are part of an engineering team developing a new medical device. The design is approved, the CAD models are complete, and the project is ready to move into prototyping.

Then a manufacturing challenge arises.

The housing does not seal as expected. The selected adhesive is not bonding reliably to the device surface. A custom gasket or insulating component is needed to protect sensitive internal parts, but your team does not have the equipment or processes to consistently manufacture it at production volumes.

This is where a material converter can help by turning a material challenge into a practical component solution.

Material manufacturers produce adhesives, foams, films, tapes, rubber materials, and other flexible materials. However, those materials often begin as large rolls or sheets. A converter transforms them into finished components designed for a specific product, assembly, or application. PGC converts materials into custom components based on customer drawings, application requirements, and manufacturing needs.

What Does a Material Converter Do?

At its core, a material converter transforms raw materials into application-ready components, providing the bridge from material selection to finished part. Depending on the project, this may involve cutting, laminating, slitting, applying adhesive, or producing parts in a format that supports efficient assembly.

Common converted components include custom gaskets and seals, spacers, insulators, adhesive-backed components, cushioning parts, thermal-interface components, precision die-cut parts, and multi-layer assemblies. A converter does more than cut material into a shape. It also integrates material selection, manufacturing requirements, quality requirements, and production scalability.

What Happens During the Converting Process?

The exact process varies by application, but most converting projects follow several common stages.

Application and Drawing Review

The process often begins with a review of the component drawing, intended function, assembly method, and operating environment. The converter may need to understand temperature exposure, contact with moisture or chemicals, surface compatibility, compression requirements, sealing needs, electrical or thermal insulation requirements, dimensions, tolerances, production quantities, and packaging preferences. Reviewing these details helps determine whether the proposed material and component design are practical for production.

Material Evaluation

Material selection plays an important role in component performance. Depending on the application, a converter may help evaluate adhesives, foams, films, rubber materials, sponge materials, tapes, thermal-interface materials, insulating materials, and other flexible substrates. The objective is to identify material options that align with the customer’s documented performance, environmental, assembly, and production requirements. Final material approval may also require testing and validation by the customer.

Process and Tooling Selection

Once the component requirements are understood, the converter determines which manufacturing process may be appropriate for the project. Die cutting is a common converting method. It can be used to produce custom shapes, openings, cutouts, and other features in flexible materials. Other processes may include laminating, slitting, adhesive application, precision cutting, and custom packaging or part presentation. The appropriate process depends on the material, part geometry, tolerance requirements, production volume, and intended use.

Prototyping and Preproduction Development

Some projects begin with prototypes or a limited preproduction quantity. This stage gives the customer an opportunity to evaluate fit, form, and function before moving into larger production volumes. Prototyping can also help identify design, material, or manufacturing changes early in the process.

Inspection and Quality Control

Finished components should be evaluated against the requirements established for the project. Depending on the part, inspection may include verification of the material, dimensions, part geometry, feature placement, adhesive construction, layer alignment, packaging, or presentation. The appropriate inspection method depends on the component, customer specifications, production requirements, and agreed quality criteria.

Production and Delivery

After the component design and manufacturing processes are approved, the converter can produce the parts in the required quantity and format. Components may be delivered individually, on rolls, kiss-cut on a liner, arranged on sheets, packaged as sets, or prepared in another format that supports assembly. The delivery format can affect part handling, assembly speed, protection, and production efficiency.

Why Do Manufacturers Work with Material Converters?

Manufacturers can often purchase raw materials directly. However, converting those materials into repeatable finished components may require dedicated equipment, tooling, manufacturing processes, and specialized knowledge. Working with a converter can help manufacturers avoid investing in new equipment, developing internal processes, or training additional personnel for work that falls outside their core production capabilities.

A converter can also help reduce the number of manufacturing steps performed within the customer’s facility. Receiving a part that is already cut, shaped, laminated, or adhesive-backed can simplify material handling, component preparation, adhesive application, assembly, and inventory management. This allows engineering and production teams to focus more resources on the primary product rather than on producing supporting component internally.

Material Utilization and Production Efficiency

Converters can evaluate part layout, material width, nesting, tooling, process selection, and production format to help reduce unnecessary material use. Manufacturers may also avoid purchasing and storing full rolls or sheets when they only require finished components. This increases the potential for improved material utilization when it comes to part geometry, material selection, tooling, quality requirements, and order quantity.

Production Repeatability

A prototype may require only a small number of parts, but full production requires a repeatable process. A converter can establish tooling, work instructions, inspection methods, and manufacturing controls intended to support consistency across production runs. This can be especially important when component geometry, alignment, adhesive placement, or material construction affects assembly.

What Information Should You Provide to a Converter?

Providing complete project information helps a converter evaluate manufacturing fit and prepare a more accurate quotation.

Useful information may include:

- A part drawing or CAD file with dimensions and tolerances

- Material specification or required component function

- Operating conditions, including temperature and environmental exposure

- Sealing, adhesive, insulation, or thermal requirements

- Target timing and applicable quality requirements

Choosing a Material Converting Partner

Selecting a converter involves more than confirming whether a supplier can cut the part.

Manufacturers should consider whether the converter can work with the required materials, support the component design, produce the expected quantities, meet documented quality requirements, and deliver parts in a format that works for the customer’s assembly process. 

Clear communication is also important, particularly when a project moves from prototype development to repeatable production. The right converting partner should help connect material requirements with a practical component design and manufacturing process.

How PGC Supports Custom Converting Projects

PGC converts materials into custom gaskets, seals, spacers, insulators, adhesive-backed parts, thermal-interface components, and other engineered components for OEM applications.

PGC works with customers to review project requirements, evaluate suitable materials and manufacturing approaches, develop prototypes when appropriate, and produce components in accordance with agreed drawings and specifications. This process helps connect material requirements, component design, production needs, and delivery format within a practical manufacturing approach.

Have an Active Project?

Manufacturers with an active component project can submit a drawing, material specification, estimated quantity, application requirements, and production needs for PGC application engineers to review.
