Materials & Core Components
· After raw materials arrive at our facility, we verify specifications, appearance, and related information.

· Many of our equipment products use stainless steel housings or main structures to improve mechanical strength, corrosion resistance, and ease of cleaning, allowing better performance in high-temperature, oily, and humid environments.

· According to different product requirements, we also select and match key components such as heating elements, thermostats, motors, transmission systems, and electrical components.
Production Process Quality Control
· During cutting, bending, welding, and assembly processes, we inspect component dimensions, structural connections, surface finishing, and assembly conditions according to product drawings and technical requirements.

· Production personnel complete the assembly of oven chambers, doors, heating systems, transmission systems, and control components based on corresponding specifications.

· For OEM and ODM products, manufacturing is carried out according to approved drawings, prototypes, or technical specifications.
Testing & Inspection
· After assembly, each piece of equipment undergoes power-on and operational testing to ensure that control panels, heating systems, motors, conveyor systems, and other functional components operate properly.

· Heating equipment undergoes temperature rise and temperature control tests. Equipment equipped with conveyors, fans, or rotating shafts is tested for smooth operation, transmission stability, and continuous working performance.

· After testing, we further verify equipment appearance, model number, voltage specifications, nameplates, logos, and customized requirements.
Packaging & Traceability
· Before packaging, we verify equipment models, quantities, accessories, and related documents. Appropriate protective measures are applied according to equipment dimensions, structure, and transportation methods.

· Through order information, equipment models, nameplates, and serial information, we provide a reliable basis for future technical support, warranty services, and spare parts matching.

· For OEM and ODM projects, related configurations and customization records can also support future repeat orders, spare parts supply, and product upgrades.
