Các công đoạn sử dụng phương pháp cắt này
Electric vehicle component manufacturing production
Automotive Radar-Absorber Sheet is processed by contour cutting to support battery sealing, motor insulation, radar absorption, optical display and camera assembly. The finished geometry must remain compatible with downstream handling and assembly.
Cut-quality control
Production teams compare accepted and rejected samples for finished dimensions, edge condition, surface cleanliness, compression behavior and assembly fit, then relate the result to corner radius, cutting path, support, compression and part retention.
Stable material and waste handling
stable support, controlled compression and protected transfer of finished components help the product and waste leave the cut zone consistently without creating a second defect after separation.

Các vấn đề cần chẩn đoán trước khi thay dao
The cut edge shows foam tearing, insulation fiber pullout, optical scratches, layer shift or incomplete profile separation
Compare blade condition, corner radius, cutting path, support, compression and part retention, material lot and accepted versus rejected samples.
Finished dimensions drift during a production run
Check feed registration, tension or hold-down, temperature, support condition, runout and when dimensions are measured.
The workpiece shifts, curls or loses functional surface quality
Review stable support, controlled compression and protected transfer of finished components, contact-face cleanliness, material direction, support and the first point where deformation appears.
Product and waste do not separate consistently
Check cut completeness, waste width, exit angle, static, extraction, collection tension and downstream transfer.

- Current blade or knife drawing, holder interface, mounting dimensions and used sample
- Material direction, support, contact faces and product or waste collection method
- Accepted and rejected samples with limits for finished dimensions, edge condition, surface cleanliness, compression behavior and assembly fit
- Trial quantity, inspection method, downstream operation, packing and annual demand
Câu hỏi về ứng dụng cắt này
Why must automotive radar-absorber sheet be reviewed as a complete material construction?
Its substrate, coating, interfaces and surface condition can respond differently to pressure, friction and bending, so nominal thickness alone does not predict contour cutting performance.
Can the blade be selected from the material name alone?
No. Confirm corner radius, cutting path, support, compression and part retention, the holder interface, production speed, support and accepted samples before fixing the blade geometry.
What commonly causes defects during contour cutting?
Material variation, unstable support, alignment error, contamination, inappropriate clearance and blade wear can interact to create foam tearing, insulation fiber pullout, optical scratches, layer shift or incomplete profile separation.
When should the finished dimensions be measured?
Record both immediate and conditioned results when recovery, residual stress, temperature, moisture or adhesive flow can change the part after cutting.
What should be recorded during a production trial?
Record the automotive radar-absorber sheet lot, setup, speed, support, blade condition, dimensions, edge observations, waste behavior and downstream acceptance.
