Secondary Processes
End-to-end finishing, joining & validation — one source, zero gaps
Painting & Coating
Painting enhances the aesthetics and performance of molded plastic parts. This process involves masking and preparing parts and then applying paint or specialized coatings to improve appearance, UV resistance, durability, or electrical interference.
- Improved aesthetics
- UV & chemical resistance
- More durable parts
- EMI shielding
Plating
Electroplating deposits a thin metal layer onto plastic parts to achieve a metallic finish. Chrome, nickel, and gold plating are common choices, offering both decorative appeal and functional benefits like improved wear resistance and conductivity.
- Metallic surface finish
- Enhanced wear resistance
- Improved electrical conductivity
- Corrosion protection
Pad / Screen Printing
Pad printing transfers 2D images onto 3D surfaces using a silicone pad, ideal for logos, text, and detailed graphics on irregular surfaces. Screen printing forces ink through a mesh stencil for flat or slightly curved surfaces.
- High-detail graphics on complex shapes
- Multi-color printing capability
- Durable ink adhesion
- Cost-effective for branding
Laser Engraving
Laser engraving uses a focused laser beam to permanently mark or engrave designs, text, and serial numbers onto plastic parts. The process is non-contact, precise, and highly repeatable, making it ideal for traceability and branding.
- Permanent, fade-proof markings
- High precision and repeatability
- No inks or consumables
- Suitable for serial numbers and barcodes
In-Mold Labeling (IML)
IML integrates a pre-printed label into the plastic part during the injection molding process. The label becomes part of the surface, eliminating the need for post-mold labeling and creating a seamless, high-quality finish.
- Seamless label integration
- No delamination or peeling
- Eliminates post-mold labeling step
- Superior print quality
Ultrasonic Welding
Ultrasonic welding uses high-frequency ultrasonic vibrations to generate localized heat at the joint interface of two plastic parts, bonding them without adhesives or fasteners. The result is a strong, clean, and hermetic weld.
- Strong hermetic seal
- No adhesives or fasteners needed
- Fast cycle times
- Clean, flash-free joints
Heat Staking (Inserts)
Heat staking inserts metal threaded inserts into plastic parts using heat and pressure. The plastic flows around the insert, creating a strong, reliable bond suitable for repeated assembly and disassembly requirements.
- Strong thread pull-out resistance
- Enables repeated fastening
- Metal strength in plastic parts
- No pre-molded holes needed
Heat Staking (Joining)
Heat staking for joining uses localized heat to deform a plastic boss or post, permanently fastening two or more components together. This method provides a tamper-evident, secure bond ideal for consumer products and electronics housings.
- Permanent tamper-evident joining
- No adhesives required
- Low tooling cost
- Suitable for multi-material assemblies
Drilling & Tapping
Post-mold drilling and tapping creates precise holes and threaded features in plastic parts where molding alone cannot achieve the required tolerances. This is particularly useful for creating fastener holes, vents, or fluid passages.
- Tight dimensional tolerances
- Thread creation in any location
- Enables fastener attachment
- Flexibility in post-design changes
Adhesive Bonding
Adhesive bonding joins plastic parts or dissimilar materials using structural adhesives, epoxies, or pressure-sensitive tapes. This method distributes stress evenly across the bond area, making it ideal for thin-walled or delicate components.
- Joins dissimilar materials
- Even stress distribution
- Sealing and bonding in one step
- No thermal stress on parts
Assembly
Full sub-assembly and assembly services combine molded components, hardware, and purchased parts into finished products. This includes snap-fit assembly, screw fastening, press-fit operations, and quality verification at each stage.
- Single-source manufacturing
- Reduced logistics complexity
- Integrated quality control
- Faster time to market
Testing, Reporting & Validation
Comprehensive testing and validation services verify that parts meet dimensional, functional, and regulatory requirements. Services include CMM inspection, pull/push testing, environmental exposure testing, and full documentation packages for regulatory compliance.
- Full dimensional verification
- Regulatory compliance support
- Detailed inspection reports
- Design improvement feedback
Packaging & Labeling
Custom packaging and labeling services ensure parts are properly protected, identified, and ready for distribution. Options include blister packs, bags, boxes, ESD-safe packaging, barcode labeling, and lot traceability documentation.
- Parts protected during transport
- Full lot traceability
- ESD-safe options available
- Custom branding and labeling

Frequently Asked Questions
Eight answers. Everything you need to commit to a project.
Factory-direct from Vietnam — zero intermediaries.
01Where is the VNcontx factory located?
100% in-house facility in Vietnam. Tooling, molding, inspection, and quality control are all executed on-site. No subcontracting, no intermediaries. Customers are welcome to audit the factory directly at any time.
02What is the standard tooling lead time?
T1 Prototype: 3–4 weeks from design confirmation.
T1 Production: 5–8 weeks depending on cavity count, steel grade, and tool complexity. Clock starts after DFM sign-off — not order placement.
03How does VNcontx handle DFM review?
Every design goes through a factory-direct DFM review by our in-house engineering team before steel is cut. Covers wall thickness, draft angles, gate location, parting line, and sink risk. A written report is issued — no surprises after tooling starts.
04How is my design kept confidential?
VNcontx signs a Non-Disclosure Agreement (NDA) before any file transfer. We adhere to international IP protection standards. File access is restricted to personnel directly on the project. Nothing leaves the facility without explicit written authorization.
05What materials can be injection molded?
Full thermoplastic library available. Structural and regulatory applications require material qualification before processing.
06What tolerances are achievable?
Standard tolerances per ISO 20457. Critical dimensions at ±0.05 mm and tighter are achievable — require explicit drawing callout and factory-direct engineering review before tool commit. Shrink rate and geometry assessed case-by-case.
07What production shot counts are supported?
Cycle ranges from 1 shot (prototype) up to 500,000+ shots. Beyond 500K, tool steel grade and maintenance schedule are assessed by our in-house team before quoting. Mold classification from Class 105 through Class 101.
08How do I request a quote?
Upload your STEP or IGES file with a 2D drawing specifying critical dimensions, material, surface finish, and annual volume. VNcontx returns a DFM report and formal quotation within 3–5 business days — factory-direct, no sales layer.
