Transparent & Translucent Materials We Machine
Selecting the right clear or translucent polymer depends on clarity targets, impact strength, temperature, chemistry, and cost. We help you choose and validate material grades.
PMMA / Acrylic
- Clarity: Best optical clarity and scratch resistance among common clear plastics.
- Applications: Display windows, light guides, sight glasses, cosmetic covers.
- Notes: Lower impact than PC; good dimensional stability; easy to polish.
Polycarbonate (PC)
- Strength: High impact strength, good clarity; suitable for guards, machine covers, lenses.
- Finishing: Vapor polishing improves surface clarity; sensitive to solvents.
- Best for: Toughness required over scratch resistance.
PSU / PPSU (Amber Translucent)
- Heat: High heat and hydrolysis resistance; repeated sterilization capability.
- Aesthetics: Translucent amber; suitable for medical, lab, fluidic components.
- Toughness: Good toughness and dimensional stability.
PEI / ULTEM (Amber Translucent)
- Temperature: High temperature capability, good stiffness and dimensional stability.
- Applications: Electrical insulation, high‑heat assemblies requiring visibility.
- Note: Excellent for demanding environments.
PET (Select Clarity Grades)
- Stability: High dimensional stability and low moisture absorption.
- Clarity: Some grades offer translucency/clarity.
- Best for: Wear surfaces and stable tolerances where moderate clarity is acceptable.
Need help selecting? Contact our engineers for material guidance.
Note: If true optical performance is required (e.g., light transmission without distortion over long paths), part geometry, surface finish process, and material selection must be considered together. We’ll advise on feasibility and finishing methods.
Finishing for Clear Plastics
We offer and coordinate finishing approaches to meet cosmetic and functional clarity goals.
As-machined finish
Ra ~1.6–3.2 μm typical (depending on toolpath and material).
Mechanical Polishing
Progressive sanding and mechanical polishing to clear finish.
Flame Polishing
Primarily for acrylic/PMMA — edges and simple surfaces.
Vapor Polishing
Primarily for polycarbonate/PC — reduces tool marks, improves transparency.
Edge Breaking & Protection
Deburring, edge breaking, and protective film application to mitigate scratches.
Custom Recommendation
Part‑specific advice based on geometry and material compatibility.
Notes: Achievable clarity and optical quality depend on material grade, geometry, wall thickness, and surface access. Flame/vapor polishing may not suit all shapes; stress‑relief steps (e.g., annealing) may be recommended to minimize crazing.
Typical Tolerances & Design Guidelines
General tolerances on machined features (material/size dependent).
Possible on small, localized features with stable materials and realistic GD&T.
Flatness/parallelism — thermal expansion and internal stress in plastics can limit achievable specs.
Design Guidance for Clear Parts
- • Use generous internal radii to reduce stress concentration and crazing risk.
- • Avoid sharp transitions; add fillets and chamfers to protect edges from chipping.
- • Consider threaded metal inserts instead of direct plastic threads for high-cycle loads.
- • Uniform wall thickness improves dimensional stability and clarity consistency.
- • Specify masked/protected faces for critical optical surfaces during handling and shipping.
We provide DFM feedback to help you balance clarity, tolerance, cost, and lead time.
