Surface Finishing

At Grefit Prototype, we offer comprehensive surface finishing services to enhance the appearance, durability, and performance of your components. Our advanced finishing techniques ensure high-quality results for both prototypes and production parts.

Custom Solutions and Quality Assurance

We tailor our surface finishing solutions to meet your specific needs, providing expert guidance and support throughout the process. Our rigorous quality control ensures that each component meets high standards of finish and performance.

What Can Grefitprototype’s Finishing Services Do For You?

At Grefitprototype, your parts only reach their full potential after passing through our specialized finishing department. Whether working with metal or plastic, from a single prototype to large-scale production, our comprehensive finishing services ensure that your project achieves the highest level of precision and quality. We provide the essential final touches that take your components from functional to flawless.

Why we need surface finishing?

Surface finishing is crucial for enhancing the appearance, functionality, and durability of products. It can improve aesthetics, protect against corrosion and wear, enhance performance properties like electrical conductivity, and contribute to product differentiation. Additionally, surface finishing can improve safety by providing non-slip or antimicrobial properties. By carefully selecting the right finishing technique, manufacturers can significantly increase the value and appeal of their products.

Our Surface Finishing Services

Anodizing

Grefitprototype specializes in anodizing aluminum, magnesium, and titanium to enhance corrosion resistance, surface hardness, wear resistance, and heat dissipation. This process not only strengthens your parts but also provides an ideal base for painting and priming, with an added aesthetic appeal. We primarily use Type II anodizing, which allows for the addition of tints and dyes for visual enhancement. For surfaces requiring extra hardness, we also offer Type III anodizing.

Painting

A top-quality paint job is key to making your product stand out. At Grefitprototype, we use premium PPG automotive polyurethanes to replicate virtually any color, tint, or hue in our climate-controlled spray room. Our skilled painters offer millions of color options, from matte to glossy finishes.

Electric Plating

Electric plating, also known as electroplating, is a process used to coat a metal object with a thin layer of another metal. This process is achieved through electrochemical deposition, where a direct electric current is passed through a solution containing metal ions. The metal ions from the solution are deposited onto the object being plated, forming a protective or decorative coating.

 

Brushing

For products that require a brand name or logo printed on their surface, pad printing offers a quick and cost-effective solution. At Grefitprototype, we emboss your desired image onto a hard rubber block, creating a stamp that imprints simple text or graphics onto flat or slightly curved surfaces. While pad printing is limited to one color at a time, it’s an efficient method for adding brand identity to your products.

Pad Printing & Silk Screen Printing

Silk screen printing is a versatile and reliable technique for applying intricate designs and multi-color patterns to a variety of surfaces. At Grefitprototype, we use a fine mesh screen combined with a custom stencil to precisely control the application of paint or ink onto your product. This method allows for detailed and vibrant images that are both durable and visually striking. Whether you need to print logos, text, or complex artwork, silk screen printing is a cost-effective option that delivers high-quality results on flat and slightly curved surfaces.

Sanding and Polishing

At Grefitprototype, sanding serves not only as a preparatory step for painting but also in achieving the final surface finish. We offer both brushed and satin finishes for metal surfaces, and our expertise extends to creating optically clear polishes on transparent plastics. Additionally, hand sanding is a crucial part of our vacuum casting process, ensuring that master patterns are meticulously prepared before producing copies.

Vapor polishing

Vapor polishing is a specialized technique used to achieve optically-clear finishes on polycarbonate (PC) plastic. This method is particularly effective for repairing minor surface defects and reaching areas that are difficult to address manually. The process involves using Weldon 4 gas to melt the plastic’s surface at a molecular level, allowing it to smooth out tiny scratches and imperfections for a crystal-clear result.

Blasting

Blasting involves projecting abrasive media onto a workpiece to achieve various effects. Common abrasives used in this process include sand, garnet, walnut shells, or high-pressure water. This technique is essential for cleaning and de-burring parts, preparing them both mechanically and chemically for subsequent surface finishes. Additionally, blasting can create distinctive textures such as frosting or pebbling. Visit our blog to explore more about other popular methods for metal surface finishing.

Color Matching

Achieving a flawless color match is no small task, which is why Grefitprototype employs advanced color spectrophotometers to measure surface color, tint, and reflectance with precision. This technology allows us to accurately replicate your color samples and ensure that Pantone or RGB colors are applied precisely according to your specifications. By leveraging this level of detail, we guarantee that your project will have the exact color match needed for a perfect finish.

Once we receive your drawings, our engineers will promptly review your custom parts. We collaborate closely with you to ensure all details are clarified before providing a quote that is both precise and cost-effective.

HOW IT WORKS

The Process of Surface Finishing

Our customers from various industry such as electronics, consumer products, agriculture, automotive, robotic, etc.

Assessment and Selection

We start by evaluating your component's material and application needs. Based on this assessment, we recommend the most suitable surface finishing techniques to enhance durability, appearance, and performance.

Preparation and Finishing Process

Once the appropriate finishing method is selected, we prepare the component by cleaning and pre-treating the surface. Our advanced finishing techniques, such as polishing, coating, or texturing, are then applied to achieve the desired result.

Quality Inspection

After finishing, each component undergoes a thorough inspection to ensure the finish meets your exact specifications. We check for consistency, durability, and appearance to ensure the highest quality.

Final Packaging and Delivery

Once the quality check is completed, the finished components are carefully packaged and delivered, ready for immediate use in your project, with enhanced performance and aesthetics.
