What Happens from Design to Delivery in Custom Assembly Machine Projects?

Our Custom Plastic Welding Automation Process at HUAZHUO

At HUAZHUO Automation, we specialize in delivering non-standard, fully customized plastic welding and automation equipment for the automotive industry. Every project follows a rigorous internal process that ensures high precision, quality, and efficiency from concept to commissioning.

1. Engineering Design & Product Analysis

Our journey begins with a deep understanding of the client’s part and production requirements.

lSenior engineers from the Design Department analyze 3D product data and welding specifications

lCustomized automation solutions are proposed

lMechanical drawings, electrical layouts, and process flow diagrams are prepared

lEach project is evaluated for material compatibility, cycle time, and tooling feasibility

2. Machine Structure Fabrication

Once the design is approved, the machine enters the manufacturing phase:

lSteel frame cutting and fabrication begins in our sheet metal workshop

lStructural welding and grinding ensure durability and dimensional accuracy

lAll machine frames undergo surface treatment before assembly

3. Mold & Tooling Precision Machining

All core molds and welding tools are machined in-house to ensure fit and finish:

lHigh-precision CNC machining centers, gantry milling machines, and lathes are used

lTolerances as low as ±0.01 mm are maintained for key components

lAll fixtures are aligned for process repeatability and fast cycle time

4. Mechanical Assembly & Electrical Integration

The final assembly takes place in our clean, organized production workshop:

lTechnicians assemble linear guides, cylinders, servo motors, and robot arms

lElectrical engineers handle wiring, I/O setup, PLC programming, and HMI interface configuration

lPneumatic and vacuum systems are installed and tested

5. Debugging & System Testing

We perform full-cycle dry runs and actual welding tests using customer parts:

lProcess validation and fine-tuning of welding parameters

lFunctional testing of sensors, vision systems, safety interlocks

lComprehensive FAT (Factory Acceptance Test) report is provided before shipment

6. Delivery, Installation & After-sales

Once tested, the machine is prepared for export with protective packaging.

 On-site installation and commissioning (optional)

 Operator training and maintenance guidance

 Lifetime online technical support, software updates, and spare parts availability
