Connecting separate processes under one production path

In many projects, the hardest part is not one single operation. The challenge is keeping plastic parts, metal parts, finishing, and assembly aligned once they move across different vendors and different schedules.

Our integrated manufacturing setup is meant to reduce that disconnect. By coordinating molding, machining, joining, and finishing in one manufacturing flow, it becomes easier to manage fit, appearance, lead time, and follow-up changes.

We do not treat this as a collection of isolated services. We treat it as a production path that needs to stay connected from component build to finished output.

Core manufacturing capabilities

Plastic molding and material handling

The department supports thermoplastic injection molding for engineering plastics such as PC, ABS, PP, POM, PBT, and PA, and also works with glass-fiber and carbon-fiber reinforced materials.

According to the current English site, annealing is also part of the capability set for relieving internal stress and improving part rigidity, with applications including precision mechanical parts, optical-grade transparent parts, and thin-wall structures.

Metal forming and precision machining

The metal-side capability set includes CNC multi-axis wire forming for compression springs, torsion springs, extension springs, clips, fasteners, and custom wire forms. The same page also lists precision stamping with press capacity from 35 to 630 tons.

For secondary machining, the department page describes multi-axis CNC milling centers, lathes, precision grinding equipment, and EDM for high-precision geometry, secondary operations after molding, and more demanding internal features.

Integrated manufacturing often comes down to how well plastic parts and metal components fit together in actual assembly, not only how each part looks on its own.

Precision stamping, CNC, grinding, and EDM

The official page describes stamping applications such as EMI shielding cases, heat sinks, precision terminals, and structural brackets. It also lists CNC machining for metals and engineering plastics, grinding for tighter surface and dimensional control, and both Wire EDM and Sinker EDM for complex cavities, narrow slots, and hard materials.

Secondary machining is often what brings geometry, tolerance, and downstream assembly requirements into alignment.

EDM remains important for narrow slots, internal features, and materials that are difficult to machine through conventional cutting alone.

Assembly and joining

Ultrasonic welding

The current English page describes ultrasonic welding as a process that uses high-frequency vibration to create frictional heat and fuse plastic joint surfaces under pressure. It is presented as a method for sealed enclosures, medical devices, and automotive components where stronger or more controlled joining is required.

Ultrasonic welding is useful when part joining needs to be controlled for strength, sealing, or repeatability.

Final assembly

The department page also describes final assembly covering plastic parts, metal components, springs, and stamped parts, with the goal of making sure function and fit match the design intent.

Assembly performance depends on whether upstream molding, machining, and part direction have already been controlled well enough to work together.

Surface finishing and post-molding work

Coating, plating, and painting

The official English page lists coating and plating as a major part of the department scope. It includes UV-curable hard coating for transparent or high-gloss components, PVD with DAH YOUNG H1800 hybrid coating equipment and CVT H2000 evaporation coating equipment, electroplating, and precision spray painting.

The homepage summary also describes this team as a one-stop finishing and assembly function covering painting, plating, ultrasonic welding, and packaging QA, with the broader purpose of shortening lead time and reducing total cost.

Finishing choices affect more than appearance. They can also affect scratch resistance, durability, conductivity, and overall product positioning.

Screen printing, pad printing, hot stamping, and laser marking

The same page also lists post-molding finishing processes such as screen printing, pad printing, hot stamping, and laser engraving or marking. These processes support graphic transfer, branding, part marking, traceability codes, and decorative finishes after molding and assembly.

Printing and marking are not only cosmetic steps. They also affect legibility, traceability, and consistency in production.

Hot stamping is commonly used when a product needs a more defined metallic or branded visual finish.

Laser marking is useful for serial numbers, QR codes, scales, and permanent product identification.

Why integrated manufacturing matters

The strongest reason customers look for integrated manufacturing is usually not because one process is unavailable elsewhere. It is because coordination becomes harder when each process is handled by a different supplier.

• Single workflow for molding, machining, joining, and finishing
• Fewer handoff gaps between plastic parts, metal parts, and final assembly
• Better control of fit and appearance across multiple process steps
• Shorter lead-time pressure when fewer vendors need to be coordinated
• Practical support for procurement and project management when the manufacturing path is easier to track

Example of an integrated workflow

The official department page gives one example: a remote control program moving through plastic casing injection molding, internal metal spring clip stamping, top and bottom case ultrasonic welding, surface painting, button function screen printing, brand logo laser engraving, and final shipment.

The exact sequence will differ by product, but the logic stays the same: build the parts, control the fit, complete the finish, and make sure the final assembly can move forward without unnecessary backtracking.
