1. Solid wood furniture production process: trial production
Before mass production of China solid wood furniture factory, in order to test the rationality of solid wood furniture product design, to ensure the feasibility of mass production and smooth, technical personnel according to engineering drawings, process documentation, and quality standards in accordance with the ratio of 1:1 to produce a sample or several pieces. Then, the quality assurance technicians test the feasibility and accuracy of the design structure, engineering drawings, process documents, samples and templates.
2. Solid wood furniture production process: first piece confirmation
The first piece is the qualified product before mass production. In the daily start-up, mold change, mold repair, equipment maintenance and material replacement, operators in accordance with engineering drawings, process requirements and quality standards to produce the first piece. If the first part inspection is not qualified, the product can not be produced. The first piece confirmation process is divided into machining first piece confirmation, assembly first piece confirmation, painting first piece confirmation, packaging first piece confirmation.
3. Solid wood furniture production process: test group
As the parts in the process of processing there must be errors, test group can test the error is reasonable. Mass production, should sample several sets of parts, may include artificial board class, solid wood class, resin class, hardware class, marble class, glass mirror class, cushion back class combined together. The test group must be thoroughly in place, to ensure that the test group is thorough, the processing workshop needs to arrange for the simultaneous production of relevant parts and components. The test group is divided into parts test group and whole test group. The parts test group is assembled from parts, such as dresser drawer panels, side panels, bottom panels, back panels and other parts of the drawer; overall test group is assembled from parts, such as dresser front frame, back frame, drawers, panels, side panels, doors and so on all try to form a complete dresser.

Operators must understand the product characteristics, work instructions, quality standards, self-inspection methods and parameters of important processes before the operation. If the operator finds abnormal quality in the independent inspection, the machine should be shut down and corrected in time.
Mutual inspection: in the production of the assembly line, the next process employees on the upper flow parts random inspection.
Patrol inspection: in the production of roving inspection, found solid wood furniture product quality abnormalities or defective products produced, require improvement or suggest shutdown, stop production, and timely correction.
