Liquid Coating
Painting for CNC Machined Metal and Plastic Parts
Formexi coordinates liquid painting for parts requiring color, gloss, environmental protection or material-compatible decorative coating. Paint system, primer, substrate preparation, cure, thickness, masking and acceptance sample must be specified.
When Painting May Be Preferred
- Custom color or gloss unavailable in another finish
- Parts requiring a primer/topcoat system
- Mixed materials needing a compatible decorative appearance
- Geometry or batch needs better suited to liquid coating than powder
Paint System, Not Just Color
A Pantone or RAL reference describes appearance but not resin, primer, chemical resistance, UV performance, flexibility or adhesion. State the service environment and governing coating system where performance matters.
Surface Preparation and Masking
Cleaning, abrasion, conversion treatment or primer can affect adhesion. Threads, fits, electrical contacts, seals and bonding areas may require masking. Cure temperature must be compatible with plastics, inserts, adhesives and prior heat treatment.
Appearance and Defect Criteria
Define A/B/C surfaces, color, gloss, orange peel, runs, inclusions, edge coverage, viewing distance and approved sample. Touch-up rules should be agreed before production.
Testing and Packaging
Adhesion, thickness, hardness, chemical or salt testing is provided only when specified and supported by the selected partner. Packaging must prevent contact marks before the coating fully cures.
Our Review Method for Painting for CNC Machined Metal and Plastic Parts Requirements
When a finish can change dimensions, hide burrs, create color variation or damage cosmetic and sealing surfaces, late finish decisions can turn acceptable machined parts into rejected final parts. For Painting for CNC Machined Metal and Plastic Parts, our engineering and quotation review coordinates machining allowance, pretreatment, masking, rack-contact location, thread and fit protection, handling and post-process inspection as one route. This helps reduce rework, approval delays and avoidable purchasing cost without turning a screening assumption into a capability guarantee.
For the Painting for CNC Machined Metal and Plastic Parts buying decision, we confirm the route only after reviewing base material, process type/class, thickness, color or texture sample, masks, critical post-finish dimensions, tests and packaging. Any unresolved item is listed as an RFQ clarification so the buyer can compare scope, evidence, price and lead time on the same basis.
Control Painting for CNC Machined Metal and Plastic Parts on the Drawing
For Painting for CNC Machined Metal and Plastic Parts, identify the base material and condition, process standard, type or class, target thickness where applicable, color or texture, pretreatment, masking and rack-contact limits. Mark the threads, bores, datum surfaces, contacts, sealing faces and fits that need protection or post-process verification.
For Painting for CNC Machined Metal and Plastic Parts, state whether dimensions apply before or after treatment and define thickness, appearance, adhesion, corrosion or certificate checks only where required. Quantity, approved-processor requirements and first-article approval then become part of price and lead-time review.
