FAQ About Surface Finishing

Find answers about turnaround times, custom masking, environmental compliance, shipping protection, and quality guarantees.

How fast can I get a quote for surface finishing?
Rally Plastic values your time. Once you upload your CAD files and specify your desired finish (e.g., Pantone color code or SPI polish grade), our engineering team will provide a comprehensive, transparent quote within 24 hours.
Can you apply finishes to specific areas of a part while leaving others bare?
Yes. Rally Plastic utilizes precision custom masking fixtures during our painting and plating processes. This ensures that critical functional areas (like snap-fits, screw bosses, or conductive contact points) remain completely paint-free while the exterior achieves a flawless aesthetic finish.
Are your painting and plating processes environmentally compliant?
Absolutely. We are committed to sustainable manufacturing. All our surface finishes, including our paints and UV coatings, are strictly RoHS and REACH compliant. We use eco-friendly materials and non-toxic processes to ensure your products can be safely exported to global markets without regulatory issues.
High-gloss finished parts are fragile. How do you protect them during shipping?
Rally Plastic treats your finished components with the utmost care. To prevent any scratching or damage during transit, we apply custom protective PE films to high-gloss surfaces and utilize tailored packaging solutions, including blister trays, custom foam inserts, and layered dividers, ensuring a 100% yield rate upon arrival.
What happens if the surface finish does not meet our approved sample standard?
We stand behind our quality with a zero-risk guarantee. Since we handle both molding and finishing internally, we maintain complete traceability. If any batch deviates from the approved Pre-Production Sample (PPS), we take full responsibility to rework or replace the parts immediately at no extra cost, ensuring your assembly line never stops.
Can you apply custom surface finishes to T1 trial samples?
Yes, we can. While the primary goal of the T1 trial is to verify mold functionality and strict dimensional accuracy, we understand you may need fully finished prototypes for marketing campaigns or investor presentations. Upon request, we can apply custom finishes—such as painting, UV coating, or plating—to a select number of T1 or T2 samples.
