Product Assembly

With five clean assembly lines, we offer one-stop services including hot-press nuts, insert assembly, component assembly, complete unit assembly, packaging, and shipping, helping customers complete the final stages of the process from plastic parts to finished product delivery.

What is finished product assembly?


Final assembly is the process of assembling components such as injection-molded parts, hardware, electronic components, seals, and packaging materials in accordance with the product’s structure and manufacturing requirements; it is a critical step in transforming a product from individual parts into a market-ready finished product.

For consumer electronics, smart devices, home appliances, automotive parts, industrial enclosures, and 3C products, reliable assembly capabilities can help customers reduce the costs associated with managing multiple suppliers, improve product delivery efficiency, and bring products to market faster.

Hongqing Finished Product Assembly Service


Hongqing operates five clean assembly lines and offers services including plastic part post-processing, component assembly, complete unit assembly, packaging, and shipping. By leveraging the seamless coordination between front-end injection molding, surface treatment, and back-end assembly and delivery, we provide our customers with a one-stop solution covering the entire process from plastic parts to finished product delivery.

Clean assembly lines


Hongqing is equipped with five clean assembly lines capable of meeting the assembly requirements for products with specific needs regarding appearance protection, assembly environment, and production stability. These lines are suitable for projects involving consumer electronics, smart hardware, home appliance components, industrial products, and 3C products.

Access Control for Air Showers


The assembly workshop is equipped with an air shower to remove dust from personnel before they enter the cleanroom, helping to reduce the entry of external dust and foreign particles into the assembly environment. For products with high aesthetic requirements, those prone to dust contamination, or those requiring clean assembly, the air shower can enhance the stability of the assembly environment and ensure consistent product appearance.

Assembly of Hot-Pressed Nuts and Inserts


For plastic products that require screw fastening, repeated disassembly and reassembly, or structural connections, Hongqing offers post-processing and assembly services such as hot-press nuts and insert installation to enhance the connection strength of plastic parts and the reliability of subsequent assembly.

Assembly of Components


Based on our customers’ product designs and assembly process requirements, we can assemble components such as plastic parts, metal parts, electronic components, seals, buttons, panels, and decorative parts, ensuring precise fit, structural stability, and consistent appearance.

Complete Unit Assembly


For products requiring complete delivery, Hongqing offers full-assembly services, integrating injection-molded parts, electronic components, metal parts, surface-treated parts, and packaging materials into finished, ready-to-ship products, thereby helping customers shorten their supply chain processes and time-to-market.

Packaging, Sealing, and Shipping


Hongqing is equipped with sealing machines that can perform product cleaning, labeling, bagging, sealing, box packing, case packing, and pre-shipment inspection according to customer packaging requirements, helping customers complete the final stages of the process from assembly to packaged delivery.
