1. Edge banding equipment
(1) Equipment factors
The main factors that affect the edge sealing quality are: 1) the operator is not familiar with the performance and operation specifications of the equipment; 2) The performance and status of the equipment is not confirmed before, during and after use; 3) The daily maintenance of the equipment is not in place, reducing the service life of the equipment, resulting in insufficient product accuracy.
(2) Equipment control measures
The quality control measures for edge banding equipment include: 1) Standardize the equipment spot inspection management system, clarify the specific methods of different edge banding machines spot inspection, and deal with the problems found in the process of spot inspection in time; 2) Establish equipment TPM management system, formulate equipment maintenance and maintenance standards, and regularly test and repair equipment according to the standards.
2. Edge sealing material
(1) Material factors
The main material factors that affect the quality of the edge sealing are: 1) the thickness deviation of the plate, the appearance quality of the plate does not meet the requirements; 2) The temperature deviation of the equipment coating shaft and the ambient temperature of the edge sealing affect the performance of the adhesive; 3) Edge band itself has color difference.
(2) Material control measures
The quality control measures for raw materials such as plate, adhesive and edge sealing include: 1) Formulating raw material control standards and raw material incoming inspection system, and doing a good job in raw material quality control and quality assurance; 2) Manage raw material suppliers; 3) Set different melting temperatures according to seasonal changes; 4) Formulate the handling and storage standards of raw materials, strengthen the protection of raw materials handling and storage process.
3. Edge sealing process
(1) Process factors
The main factors affecting the quality of edge banding are: 1) there is no enforceable product quality standards, operating standards and operating procedures; 2) There is no first piece inspection system after the equipment is started, repaired, stopped for more than 2 hours and the raw material is replaced.
(2) Process control measures
The quality control measures for the edge banding process include: 1) Establish the edge banding quality standard as the technical basis for the edge banding quality inspection; 2) Make the edge-sealing operation instructions, and require the operator to operate in strict accordance with the operation instructions; 3) The implementation of the first piece of testing system, each equipment in the boot, maintenance, shutdown more than 2 hours, after the replacement of raw materials to produce the first product should be the first piece of inspection; 4) Implement the sampling inspection system, extract the appropriate amount of edge sealing plates for inspection according to the stipulated sampling plan, and improve the quality according to the test results.
