Why Choose PET for Extruded Components?
PET (Polyethylene Terephthalate) is engineered for applications demanding stringent mechanical performance, tight profile stability, and chemical resistance under harsh environmental demands.
Dimensional Stability
Extremely low moisture absorption ensures parts retain tight geometries and physical structure under varying ambient conditions.
Mechanical Strength
High tensile modulus and load-bearing rigidity make PET ideal for durable structural profiles and track assemblies.
Chemical Resistance
Resists degradation from alcohols, oils, greases, and standard solvents, serving heavy industrial and food-contact environments.
Surface Quality
Provides pristine cosmetic clarity and smooth low-friction surfaces suitable for exterior consumer components and sliding tracks.
Custom Die Design & Tooling Optimization
The structural accuracy and consistency of an extruded part begins with precision-machined tooling. Plasticpartsmfg manages complete in-house die design and fabrication to ensure the cross-section of your profile conforms precisely to engineering schematics.
During the initial design review phase, our technical team analyzes your 2D and 3D CAD files to identify potential flow bottlenecks, uneven wall thickness ratios, or complex undercuts. We balance the flow channel geometry within the die head to guarantee uniform melt delivery, mitigating warpage, residual stress, and out-of-tolerance profiles.
Design for Manufacturing (DFM) verification is conducted before cutting steel, protecting tooling budgets and accelerating lead times.
Secondary Operations & Integrated Finishing
Extruded plastic profiles often require secondary post-processing before ready for final assembly. We offer integrated downstream operations under one roof.
Precision Cutting
High-speed in-line and precise off-line guillotine, saw, or knife cutting to tight linear tolerances.
Mechanical Machining
Precision drilling, automated punching, routing, and slotting for mechanical mounting points.
Sub-Assembly
Installation of sealing gaskets, PSA tape application, and multi-component composite bonding.
Custom Packaging
Bulk palletization, protective interleaving, barcoding, and custom kit preparation for seamless fulfillment.
Quality Control & Inspection Standards
Plasticpartsmfg executes strict verification routines to prevent drift and ensure dimensional repeatability throughout production runs. Calibrated digital micrometers, optical profile projectors, and coordinate measuring instruments verify wall thickness and profile cross-sections.
1. First Article Inspection (FAI)
Complete multi-point verification of trial runs against 2D dimension prints prior to full production authorization.
2. In-Process Monitoring
Hourly operator checks and automated visual inspection monitoring profile wall consistency and cooling behavior.
3. Final Inspection & Sign-off
Audit of cosmetic finishes, cut lengths, packaging integrity, and release reports prior to container loading.
