Materials

At Upper Prototype, we understand that material selection defines performance, durability, and user experience.
Our engineering team supports you from the earliest design stage — helping select the right materials for prototypes, pilot builds, or bridge production — ensuring the perfect balance between mechanical strength, aesthetics, and cost efficiency.

Whether you need high-clarity plastics for camera lenses, heat-resistant polymers for EV chargers, or lightweight metals for sensor housings, we deliver parts that match real-world

Plastics

Application Materials: ABS, PC, PC/ABS, PA, POM, PP, PE, PBT, PEEK, PEI, TPE, TPU, TPV, TPR – covering a wide range of common and engineering-grade plastic granules, suitable for functional prototypes, structural parts, and cosmetic components.

Tolerance Standard: In accordance with ISO2768-MK and NFT58000 Normal Class for precision and repeatability.

Surface Treatment Options: Silkscreen printing, pad (movable) printing, electroplating, polishing, satin texture finishes, and laser carving – offering versatile cosmetic finishes to meet your industrial or consumer-grade requirements.

Metals

Application Materials: Aluminum (6061, 7075), Stainless Steel (303, 304, 316), Mild Steel, Brass, Copper, Magnesium Alloy, Zinc Alloy, Titanium – ideal for high-strength, thermal, and mechanical performance in industrial applications.

Tolerance Standard: Machined to ISO2768-MK or customer-specific GD&T standards for critical dimensions and fit.

Surface Treatment Options: Bead blasting, anodizing (Type II & III), powder coating, black oxide, nickel plating, zinc plating, and polishing – supporting both aesthetic and corrosion-resistant needs across industries.

Surface Finishes & Coatings

Enhance appearance, grip, or environmental resistance.

• Polishing / Sandblasting / Brushing – improve surface texture

• Painting & UV Coating – enhance color and gloss

• Anodizing (Aluminum) – for durability and aesthetics

• Laser Engraving & Printing – branding or markings

• Electroplating / Nickel Plating – conductivity & corrosion protection
