With our experienced in-house skills and advanced facilities, we try our best to ensure the color, texture, gloss, and surface finish of parts and exceed your expectations.
Our Parts Finishing Capabilities
Whether it is CNC machined, urethane cast or 3D printed parts, to gain an accurate appearance of your final product, the prototype must undergo a rigorous post finishing process, which describes the final steps required before a product can be truly brought to life.
SHD provides an integrated parts finishing service to meet your diverse needs. With our experienced in-house skills and advanced facilities, we try our best to ensure the color, texture, gloss, and surface finish of parts and exceed your expectations.
Common Post Processing
Contact us to learn more about how we can help you with the parts finishing processes outlined below.
Sanding and Polishing
Smooth sanding can remove machining marks, burrs, machine lines, and adhesive marks on the surface of the parts. The flatness of the part will be improved and roughness will be reduced to create a smooth and uniform look.
High polishing process is used for a mirror finish on normal plastic, metal parts, and clear acrylic and polycarbonate parts, to achieve a precise uniform flat surface and professional-grade gloss, or to enhance the optical clarity of clear parts.
Sanded to 600 grit sandpaper surface finish is Ra 0.8 μm;
Sanded to 1000 grit sandpaper surface finish is Ra 0.4 μm;
Mirror polished and clear polished surface finish is Ra 0.1-0.05 μm.
Machined Finish
Machined parts will have marks that follow the path of the cutting tool. The machined finish is that a smooth surface, created by a machine without polishing work, only needs a little handwork to clear the bur, the part could be finished and delivered quickly soon after off the machine.
The standard machined surface roughness is Ra 3.2-1.6 μm;
The smooth machined surface roughness is Ra 1.6-0.8 μm;
The super-finished surface roughness is Ra 0.8-0.2 μm.
The finishing will increase the cost of producing a part, as extra machining steps and tighter quality control are required.
Hand Finishing
From de-flashing to gluing, filling, modifying, adding inserts, pre-fitting, measuring, and assembling, our handcraft specialists focus on every engineering detail and design specification.All post-processing is created in-house, but our team can also work with client-supplied components to finish and assemble as needed, include mating and fitting parts. Normally, this reveals engineering hurdles that are not apparent in CAD design. We will help overcome these challenges, offer solutions and achieve a finished project.
Blasting
Bead blasting adds a uniform matte surface finish on a machined part, removing the marks of tool and sandpaper. It is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, or remove surface contaminants. The size of the air pressure and the size of the glass beads are the main process parameters. Glass beads come in different sizes from #80 to #220.
Painting
Paint Colors:
We uses Pantone Matching System and RAL Classic System to match custom colors or paint samples. We can also do two-color or multi-color painting to obtain a more complicated appearance looks like 2K molding.Paint Finishes:
We can supply different paint finishes, in matte, flat, semi-gloss, glossy finish, or satin finish. We can also simulate a specific Mold-Tech texture or soft touch to achieve a feel similar to the texture or over-molding of injection molded parts.
Functional Coatings:
UV coating is able to resist ultraviolet radiation and protect the underlying material to enhance the durability and wear or scratch resistance. With EMI, the coating is used to shield or contain electronic equipment from magnetic fields or interference.
