10 Ways to improve plastic component performance and prevent failure

  Large plastic OEM parts used in demanding applications must meet regulatory standards and tight assembly requirements, plus withstand repeated cleaning cycles and daily use. Thermoforming delivers cost-effective, durable, high-performance components.

Achieving long-term success starts early in the development process. An experienced thermoforming partner can help you. These 10 tips will help you optimize quality, consistency, and reliability from concept through production.

1. Select the Right Material for Long-Term Performance

Choosing the appropriate resin helps ensure durability, chemical resistance, and appearance retention throughout
the product’s life cycle. Best practice: Match resin properties to the application by considering mechanical loads, environmental exposure, cleaning chemicals, and end-use requirements.

2. Start with High-Quality Thermoplastic Sheet

Consistent, high-quality sheet supply supports forming stronger, more reliable parts from run to run. Best practice: Have your thermoformer source materials from trusted suppliers and verify material specifications through certification reviews.

3. Design Parts to Minimize Stress

Well-designed geometry improves structural integrity and maintains more even wall thickness, which promotes
dimensional stability. Best practice: Use generous radii and smooth transitions to support balanced forming and cooling.

4. Incorporate Proper Draft Angles

Proper draft angles improve manufacturability and support consistent part release during forming. Best practice: Include adequate draft on vertical walls to improve repeatability, cosmetic quality, and part release.

5. Optimize Draw Ratios Early in Design

Balanced material distribution improves wall consistency, appearance, and structural performance. Best practice: Evaluate draw ratios during the DFM (design for manufacturing) phase to optimize geometry before tooling begins and be sure to use adequate starting gauge.

6. Align Tolerances with the Forming Process

Realistic tolerances help improve yield and control production costs. Best practice: Focus tight tolerances on critical functional features while aligning overall specifications with thermoforming capabilities.

7. Maintain Controlled Forming Conditions

Validated processing conditions support consistent, high-quality parts throughout production. Best practice: Work with a thermoformer that monitors heating, cooling, and forming parameters using established process controls and quality systems.

8. Plan for Secondary Operations and Assembly

Considering downstream processes early helps improve assembly efficiency and final product performance. Best practice: Incorporate trimming, bonding, machining, and assembly requirements into the original DFM strategy.

9. Collaborate Early with Your Thermoforming Partner

Early supplier involvement helps streamline development and improve manufacturability. Best practice: Engage your thermoforming partner during design to review tooling concepts, materials, tolerances, and production strategies.

10. Validate Quality and Reliability Before Launch

Comprehensive testing helps confirm long-term performance in real-world environments. Best practice: Conduct dimensional inspections, environmental testing, chemical compatibility studies, and life-cycle testing prior to production run.

Next step: The right partnership puts it into practice

Validating your part’s performance early in the development process is essential for long-term success. Partnering
with an experienced thermoformer will help you bring durable, high-quality OEM components to market while reducing
risk and improving production efficiency.
