Laser Cutting of Composite Parts with In-House Fixtures

At MDC Mould, our commitment to excellence in composite part processing is reflected in every step of our workflow — including the precision trimming of molded parts. One of the critical stages in composite production is post-molding trimming, and we’ve taken this further by integrating high-precision laser cutting with custom-designed, in-house-built fixtures.

Why Laser Cutting for Composite Parts?

Laser cutting has become a go-to solution for SMC parts and other composite components that require high accuracy, clean edges, and minimal material disruption. Unlike mechanical trimming methods, laser technology allows us to maintain the structural integrity of molded parts while producing highly accurate edges with tight tolerances.

In-House Fixtures: The Backbone of Consistency

Our in-house engineering team designs and manufactures laser cutting fixtures specifically tailored to each composite part geometry. This offers several key advantages:

• Stable Positioning: Fixtures eliminate part movement during cutting, ensuring dimensional accuracy.
• Repeatability: Identical results across multiple batches, ideal for mass production of composite parts.
• Contour Precision: Fixtures enable precise edge definition for complex curves and cutouts.

Preserving Material Performance

Composite materials like Sheet Molding Compound (SMC) require careful handling during finishing processes. Our laser systems are calibrated to prevent heat damage, delamination, or surface distortion. This ensures that the mechanical properties — such as tensile strength and impact resistance — remain unaffected.

Applications of MDC's Laser-Cut Composite Parts

• Automotive: Trunk boards, battery covers, splash shields
• Energy: SMC battery enclosures and switchgear panels
• Sanitary Ware: SMC bathroom panels, wall structures
• Appliances: Electrical enclosures, cable trays, housings

Why MDC?

With over 20 years of experience in SMC mould and composite mould development, MDC understands the complete process — from molding to trimming. By designing not only the composite moulds but also the cutting fixtures, we ensure vertical integration and control over every aspect of production quality.

Conclusion

Laser cutting, when combined with MDC's proprietary fixtures, results in unmatched efficiency, edge quality, and production repeatability for composite parts. Whether you're producing automotive panels or industrial housings, our integrated tooling and laser cutting approach ensures your parts are trimmed to perfection.
