Assembly

In plastic product assembly, modular design is an industry mainstream, offering simplified post-maintenance and rapid component replacement. We pre-assemble discrete parts into fully functional modules per customer needs. Upon receipt, customers can directly integrate them into final assembly—no extra handling of individual components—shortening time-to-market and enabling agile market responses.

In essence, provide discrete parts and assembly specs (or artisanal manufacturing requirements). We manage the entire modular assembly process: component inspection, precision assembly, and preliminary functional testing. No need to build an in-house team or master assembly skills—you’ll get compliant, ready-to-integrate modules. This saves time/labor costs, mitigates unprofessional assembly risks, and lets you focus on R&D and market expansion.

CHOOSE ARTISAN - NO RISK

By choosing our modular assembly service, customers can gain three core benefits: "cost reduction, efficiency improvement, and peace of mind" — each directly addressing key needs in production and market competition. These benefits can be specifically broken down into four practical gains:

Direct cost savings & reduced operational pressure:
No need for additional resource investment in the assembly phase, significantly cutting both explicit and implicit costs.

Dramatically shortened cycles & seizing market opportunities:
Helping customers skip tedious processes to accelerate the entire workflow from production to product launch.

Mitigated assembly risks & guaranteed product quality:
A professional team oversees the entire assembly process, reducing customers’ concerns about quality and after-sales issues.

Focus on core business & enhanced competitive advantages:

Customers can shift efforts away from non-core assembly work to focus on higher-value tasks.

Ultrasonic welding technology:

Ultrasonic plastic welding is a thermoplastic joining process. It uses 30–40 kHz high-frequency vibration to melt contact surfaces via friction, then forms robust joints meeting IP65/IP67 ratings after pressure holding, cooling and solidification. Efficient, clean and precise, it is a core mass-assembly technology for precision electronics, automotive lightweighting and medical consumables.
We will offer customized welding solutions: based on the material, structure and production capacity requirements of the customer's plastic parts, we will specially design and customize welding tools. For each welding production, we will first make 10 samples, then conduct tests according to the customer's requirements. And send them to the customer for confirmation. After confirmation, we will arrange for mass production.

The table above is just for general reference; adjustments will be made based on the specific requirements of each project.
