Standard forgings factory production process

Forgings factory should be in accordance with the ISO9001 standard established quality system, and through the certification center audit certificate. All departments of the forging plant strictly implement the provisions and requirements of quality documents and technical documents such as "Quality Manual", "Procedure Document", earnestly perform their quality responsibilities, and effectively carry out various tasks of forging production.

I. Forging production tasks:

The sales department shall prepare the "Production Task List" according to the contract signed with customers. The production department shall prepare drawings to clarify the technical requirements of forgings products according to the contract requirements. According to the material and performance requirements, the blanking process, forging process, heat treatment process shall be developed, and the relevant departments shall be issued according to the requirements.

Three, forging production quality control:

The inspector inspects each step of the process, the qualified products shall follow the transfer sequence signed by the inspector, and the unqualified products shall follow the company's procedure document "Control Procedure of nonconforming Products".

1. Sawing and blanking: sawing and blanking shall be strictly in accordance with the blanking Task List, and inspection records shall be made, and batch sawing shall be performed after qualified.

2, heating: different materials, different furnace number of products can not be heated with the furnace.

3, forging: the operator according to the drawings for forging, forging process with infrared thermometer control forging temperature.

4, heat treatment: according to the periodic verification of thermocouple, temperature instrument. Strictly according to the heat treatment process of the temperature rise rate, heat preservation temperature, heat preservation time and other technical parameters and reasonable cooling methods.

5, machining: according to the drawings for production and processing, the first inspection after the mass production. During the process of machining, inspectors carry out inspection on the forging products.

6. Pre-packaging inspection: full-time inspectors shall check the size, surface quality and identification of the forged parts after machining strictly in accordance with the drawings, and then carry out PMI re-inspection of the products to prevent material confusion.

7, packaging process: according to customer requirements for anti-rust treatment (oiling, dipping paint, etc.), operators according to the requirements of self-inspection, full-time packaging inspectors according to the requirements of anti-rust treatment, surface quality of the first inspection, inspection, process inspection, qualified into the packing process, otherwise rework processing.

Four, forging qualified product control:

Forgings factory to appear unqualified forgings products, inspectors mark and isolate, fill in the "Unqualified Treatment form" to the authorized personnel to deal with, strictly in accordance with the "unqualified product Control procedures" implementation, to ensure that the unqualified forgings are identified and controlled, to prevent their unexpected use or delivery.
