High-Quality Assembly & Finishing
Ichiplas provides a range of high-quality assembly and finishing processes to enhance the appearance and protection of your plastic parts, from spray painting to specialized printing techniques. Our professional engineering team can advise on the most suitable secondary processes to achieve your desired aesthetic and functional outcomes.
The Ichiplas Advantage
High-Quality Finishes
Spray Painting
Consistency and Protection:
- Application of a single, uniform color to plastic parts
- Provides an additional layer of protection
- Suitable for a wide range of part geometries and surface finishes
Tampo Printing
High-Precision Customisability:
- Printing of intricate 2D designs onto 3D plastic parts
- Suitable for parts with complex shapes and textures
- Excels at reproducing detailed graphics and logos
Silk Screen Printing
Large-Scale Efficiency:
- Cost-effective way to apply graphic designs
- Suitable for parts with flat or simple geometries
- Can accommodate a wider print area compared to tampo printing
Other Finishing Examples
Ultrasonic Welding
Ultrasonic welding is a specialized secondary process that Ichiplas utilizes to seamlessly join plastic components, creating high-quality, durable assemblies.
Ultrasonic welding uses vibration-induced heat to fuse two plastic parts together, resulting in a strong, visually appealing bond without the need for additional fasteners or adhesives. Key benefits include:
- Fast, high-throughput process
- Relatively safe indirect heating method
- Ability to weld parts made of different materials
- Produces a near-invisible, high-quality seam
End-to-End Manufacturing
Secondary Assembly
Comprehensive in-house secondary assembly services to bring your plastic parts to their final, completed state.
- Assembly and sub-assembly of plastic components
- Identification and correction of manufacturing defects
- Integration of non-plastic parts (e.g., electronics, hardware)
- Additional finishing services performed as required
Frequently Asked Questions
What finishing processes do you offer for injection molded parts?
We offer spray painting (single and multi-colour), tampo printing (pad printing for logos and detailed graphics on 3D surfaces), silk screen printing (cost-effective for flat or slightly curved surfaces), and texture finishes applied during molding via mold surface treatment.
What is tampo printing and when should I use it?
Tampo (pad) printing transfers ink from an etched plate onto a 3D surface using a silicone pad. It's ideal for printing logos, text, or detailed graphics onto curved, recessed, or textured plastic surfaces where screen printing can't reach. Common applications include control panel markings, product branding, and regulatory text on consumer electronics and medical devices.
Do you offer full assembly services — not just individual parts?
Yes. Ichiplas provides complete sub-assembly and final assembly services, including ultrasonic welding, adhesive bonding, mechanical fastening, cable/wire integration, functional testing, and retail packaging. This one-stop approach eliminates the need to ship parts between multiple vendors, reducing lead time, logistics cost, and quality risk.
Can you match specific Pantone or RAL colours for spray painting?
Yes. We colour-match to Pantone, RAL, or custom colour specifications. Our spray painting process includes colour development, sample approval, and documented colour control throughout production. For critical cosmetic applications, we recommend providing a physical colour standard (colour chip or approved sample) for reference.
What is ultrasonic welding and when is it used?
Ultrasonic welding uses high-frequency vibrations to create a molecular bond between two plastic parts without adhesives or fasteners. It produces a strong, clean, hermetic seal and is commonly used for enclosures that need to be sealed (waterproofing, dust-proofing), medical device housings, and consumer electronics casings. The process is fast and highly repeatable.
