FINISHING

Reduce cost, decrease weight and improve quality – with the optimal finishing you can get a competitive edge

Finishing refers to the machining of structural core materials. You can choose from a wide range of cuts, grooves and perforations in different patterns, which, when combined and customized, will optimize the final solution.

Why finishing?

Depending on the geometry, manufacturing process or specific component requirements, the selected finishing will have an important part to play in a successful result.

• Lower weight with the right grooves and perforations
• Cost savings – savings in consumables, resin, inlets, flow medium etc.
• Formability to adapt to mould surface
• Controlled /Repeatable quality
• Faster and secure resin flow in the vacuum infusion process
• Ensures air evacuation in vacuum infusion or vacuum bonding operations
• Improves surface finish of final parts

Why finishing from Diab?

Diab is a world-leading supplier of sandwich core materials, with long experience in developing finishing solutions. Diab has pioneered many areas, including infusion and vacuum bagging. With in-depth technical knowledge in most manufacturing methods for composites, we understand what criteria are essential for the finishing to fit the purpose. We select the most appropriate one from our wide selection of finishes for form and/or flow, based on the requirements.

Selecting the optimal finishing

The complexity of the component and the curvature of the mould influence which core finishing fits best into the mould shape, with a minimum of spring-back and reduced resin consumption. Together with the geometry and expected performance of the product, it is crucial to analyze the finishing used for each manufacturing method used. The choice of finishing will have a strong impact not only on the manufacturing of the product but also on its final performance. 

Diab offers a wide range of cuts, grooves and perforations in different patterns, serving several purposes: Form, Flow, and Flow & Form.

Diab also offers an innovative core-slitting technology to cut the material into extremely thin sheets with very tight tolerances. The benefits include a very smooth surface finish, 3D formability and decreased resin uptake – up to 30% depending on the core type and grade.
