                  | 产品质量控制 Quality Control

  江苏金源锻造坚持以质量为先,服务至上的原则为广大的客户提供长期,优质的锻件。公司内部对质量的控制有极为严格的程序。大致可分为三个步骤:原材料进厂检验,制造过程的中间检验,最终成品检验。并对所有测量器具,仪表进行定期检测。

  1. 原材料进厂检验:所有进厂原材料需经过初步化验后才能入库。所有采购钢材的厂家必需经过认证。保证对原材料进行100%的目测检查,对部分钢材进行火花测试。并根据客户的需要对钢材进行化学,物理性能方面的测试。所有的钢材进行分类堆放,并注明不同的等级。
  2. 中间检验:公司在生产制造过程的每个环节中都设有中间检验过程,包括模具,下料,锻造,加工,热处理。为满足客户的不同需求,根据专业角度及实际操作,各个车间或过程的检测有其各自的标准。

    ■ 模具:模具的检验贯穿整个过程,在生产前要进行严格的尺寸检测,并在生产过程中进行定时观察,以及在生产后进行相应的检测处理。并建有台帐,以备查看或作为参考之用。
    ■ 下料:所有下料件的重量都进行复核。对需回火后进行火焰切割的钢种,严格按照程序进行温度的控制。
    ■ 锻造:锻造炉设有仪表温控,以确保始锻温度,防止过热,过烧现象,操作技工进行定时目测,并使用红外线测温仪测定终锻温度。
    ■ 加工:对加工的锻件严格按照图纸进行100%的检验。
    ■ 热处理:聘有专门的高级工程师进行工艺的设定及流程的控制。并定时进行硬度,金相,晶粒度的抽检。所有的热处理锻件均配有温度仪表控制盘,并建有台帐,以备查看。

  3. 最终检验:所有的锻件均按照客户的技术要求进行相应的检验
    ■ 表面缺样检验
    ■ 尺寸检测,包括外形尺寸,同心度
    ■ 热处理检测(根据客户要求)
    ■ 探伤检测(根据客户要求)
    ■ 化学成分及机械性能测试(根据客户要求)
    ■ 金相检测(根据客户需求)
    ■ 硬度检测(根据客户要求)
    ■ 包装(根据客户要求)

Quality Control:
Jinyuan Foring has its own inspection plan for all forged products and its processes at different stages of production.

1.    Incoming Material Inspection
All the material coming to the company from different sources has to undergo the inspection and testing as per inspection plan before it goes to stores.
Raw material incoming from the approved steel mills are kept in the stock yard and 100% visual examination and spark testing is done.
Chemical, metallurgical and physical testing is also carried out as per the plan or instruction of the customer.

2.    Process Inspection
Inspection is carried out at every stage of production at different stages e.g. Die Shop, Cutting Shop, Forge Shop, Heat Treatment Shop.
Each shop or processing dept has its own inspection plan to satisfy the customers’ needs depending upon the experience and expertise.

  • Die Shop : Dies are checked thoroughly before dispatch for production and reports are kept in file for reference.
  • Cutting Shop : All the cut pieces are checked for the required cut weight as needed to produce particular parts. The temperature of alloy steel is strictly controlled for fire cutting.
  • Forge Shop : Temperature in furnace is controlled by the temperature controlled provided with each and every furnace. 100% visual hot inspection is done for forging defense, weight and at specified intervals.
  • Machining:100% checking for dimensions and straightness.
  • Heat Treatment: Personals responsible for the process under direct supervision of qualified metallurgies and experienced chemist and skilled workers are working as per the work instruction and inspection plan. Heat treatment furnaces are equipped with temperature indicator and controller.  Certain pieces are selected from each lot of components passing through the process of heat treatment and are tested to confirm the hardness, microstructure, grain size of the lot as per need of the customer.

3.    Final Inspection :
All the forged parts coming this shop are following inspection carried out as per plan.

  • Visual inspection for scale pit, folds, unfeeling etc.
  • Dimensional inspection : critical dimensions like thickness and references points for 1st operation at the customers end are checked 100%.
  • Heat-teatment process is check as per customer requirement.
  • Ultrasonic test: as per customer requirement
  • Chemical and mechnical tests: as per customer requirement
  • Microstructure inspeciton as per customer requirement
  • Hardness test; as per customer requirement
  • Layout : Some of the piece/lot are fully laid out for dimension as per the drawing before dispatch.
  • Packing : Packing of the forgings and dispatches are made as per customer requirement.
