How to do well the quality control and management of raw material
purchase in caster industry
Castor raw materials are very important to the production of castor
enterprises and are the basis to
ensure the product quality of castor enterprises. Experts believe
that caster enterprises need to
control the procurement quality of raw materials and ensure product
production quality and safety
from the aspects of evaluation and selection of raw material
suppliers, strengthening the acceptance
of raw materials before warehousing, and improving the quality of
warehouse management.
1, Classification of raw materials and evaluation and selection of
suppliers
1. Production raw materials shall be subject to classified
management and highlight key points
Caster enterprises need a wide variety of raw materials, but
different raw materials have different
effects on the product quality. In order to facilitate the key
control of procurement quality, raw
materials shall be classified and managed according to the impact
of raw materials on product
production quality.
It is generally divided into three categories:
Class a raw materials: refer to raw materials that may have a
direct and significant impact on product
production quality (such as direct impact on key functions and
performance of products) in the process
of production and use.
Class B raw materials: refer to raw materials that may have an
indirect or important impact on product
quality in the process of production and use.
Class C raw materials: refer to raw materials that are generally
auxiliary parts and have a general or
slight impact on product quality.
2. The evaluation practice of raw material suppliers shows that
whether the quality of purchased raw
materials is stable depends largely on the quality management level
of suppliers. Therefore, the
quality assurance capability of suppliers providing various raw
materials shall be evaluated before
procurement.
(1) Evaluation of class a raw material suppliers
The evaluation of class a raw material suppliers is the key point.
Generally, it is necessary to conduct
on-site investigation and evaluate the operation status of their
quality system, past supply, handling
and rectification ability in case of abnormal supply quality, as
well as the ability of on-time delivery
and delivery quantity, the cost performance of their products,
their after-sales service ability
(including after-sales service attitude, timeliness and effect),
etc. At the same time, we should
also evaluate the quality of raw materials by consulting the data
provided by the supplier,
investigating and understanding from other customers of the
supplier, testing and trial using the
raw material samples provided, and regularly analyzing the results
of the quality of raw materials
provided.
(2) Evaluation of class B and C raw material suppliers.
Generally, the purpose of supplier evaluation can be achieved by
consulting the data provided by
the supplier, testing and trial using the raw material samples
provided, and analyzing the results of
regular analysis of raw material quality. For the evaluation of
class B raw material suppliers, the
procurement department shall propose the "evaluation list of class
B raw material suppliers" and
provide the relevant data of class B suppliers, or the quality,
service, price and other data and
information such as the inspection and use of class B raw materials
in the past, which shall be sent
to the relevant departments of technology, manufacturing, quality
and finance for countersignature
(review) and submitted to the senior management for approval; For
the evaluation of the capability
of class C raw material suppliers, the procurement department shall
put forward the "evaluation list
of class C suppliers", which shall be countersigned by quality,
finance, etc. and signed by the manager
of the procurement department.
1. Selection and determination of raw material suppliers qualified
raw material suppliers shall be
determined through selection. Obtaining a qualified raw material
supplier depends on the above
evaluation results of the quality assurance ability of each
supplier and factors such as production
and use, price, reputation and so on. Therefore, in the final
determination of suppliers, several
suppliers of the same raw materials should be selected for
comparison, especially when the
production and use conditions and the quality assurance capacity of
each supplier are basically
the same.
2, Strictly control the incoming of raw materials. Purchasing raw
materials from qualified suppliers
is not everything. A qualified supplier only indicates that the
supplier has the basic conditions to
provide raw materials with relatively stable quality. It is
uncertain whether there is a shortage in the
quantity of raw materials actually delivered and whether the
quality can meet the production
requirements. Therefore, the incoming quality of raw materials
shall be strictly controlled according
to the following requirements before entering the factory.
3. Acceptance of raw materials without inspection. The acceptance
shall be conducted according to
the raw material purchase contract, the quality certificate,
material certificate and other quality
certificates accompanying the goods; For individual low value
consumables that are difficult to issue
corresponding certificate of conformity and material certificate,
samples must be provided in advance.
Raw materials without certificate and material certificate shall be
rejected for acceptance and
warehousing.
