The quality requirements for the production of engineering plastic plates and rods usually include the following aspects:

　　1. Physical performance indicators: the physical properties of engineering plastic plates and bars are key indicators of their quality. Common physical performance indicators include tensile strength, bending strength, impact strength, hardness and so on. Different engineering plastics for the requirements of these indicators will be different, usually in the production process need to carry out the appropriate tests to ensure that meet the required standards.

　　2. Size and appearance requirements: engineering plastic plates and rods in the production process need to maintain a certain size and appearance requirements. This includes dimensional accuracy, flatness, straightness, surface finish and other aspects. These requirements need to be strictly controlled in the production process to ensure that the product meets the specified standards and can meet the requirements of use.

　　3. Chemical performance requirements: the chemical performance of engineering plastic sheet and bar is also need to pay attention to. For example, chemical resistance, temperature resistance, insulation properties. These performance indicators may vary for different engineering plastics, the production process needs to control the ratio of raw materials and production process parameters to ensure that the product can meet the corresponding chemical performance requirements.

　　4. Environmental requirements: In the production process, the environmental requirements should not be ignored. Including the choice of raw materials, waste disposal in the production process, energy consumption and so on. The production of engineering plastic plates and rods should meet the environmental requirements and take energy-saving and emission reduction measures to reduce the impact on the environment.

　　It should be noted that different types of engineering plastic plates and rods have different production quality requirements, the specific production quality requirements should be determined according to the relevant standards and norms, and the corresponding testing and control in the production process.
