What Are Secondary Operations?

Secondary operations are post‑molding steps that improve function, appearance, or readiness for assembly. Typical services include trimming, texturing, painting, printing, inserting metal hardware, bonding or welding, dimensional verification, and final kitting—reducing vendors and accelerating time to market.

Secondary Processing for Injection Molded Parts

Our in-house secondary operations enhance both the function and appearance of molded parts. All post-processing services comply with SPI Mold Surface Standards, delivering consistent quality, precise detailing, and finishes tailored to your project requirements.

FAQs

What information do you need to quote secondary ops?

2D drawings or callouts for finishes, color targets (Pantone/RAL), any paint stack, texture code (SPI/VDI), insert type/qty, labeling/packaging requirements, and inspection level.

Can you color‑match my brand color?

Yes. We can match molded‑in colorants or paint to Pantone/RAL; we recommend sending a master chip for best results.

Will ultrasonic welding or inserts warp thin parts?

We design fixtures and set energy/time to protect geometry. For very thin walls we may recommend adhesive bonding or redesign of ribs.

Can you provide PPAP or FAI?

Yes—PPAP Level 1–3, FAI reports, and COA are available. Tell us which documents you need before kickoff.

What’s the fastest way to move from prototype to packaged product?

Approve textures and colors on a small pilot batch, lock SOPs, then run production with pre‑approved labels and packaging to avoid rework.
