Provide all kinds of industrial machinery products testing certification

It mainly includes agricultural machinery, mining equipment, metallurgical equipment, power equipment, chemical equipment and working mother machinery and other manufacturing industries. Machinery manufacturing industry is the heart of the industry, it industry, agriculture, transportation, national defense, etc. To provide technical equipment, is the material of the national economy and defense modernization technology base, therefore, machine-building industry developed or not and machine and equipment level of self-sufficiency is to measure a country's economic development level and the real symbol of the levels of science and technology. There are many categories of machine manufacturing, which has become the largest industrial system with dozens of independent production departments. Because of the complex structure of machine products, parts and components, strong technology, so the implementation of production specialization, standardization, automation for the development of machine manufacturing industry is of great significance.

Product range:

Agricultural machinery, mining equipment, metallurgical equipment, power equipment, chemical equipment, digging machinery, shovel transport machinery, construction lifting machinery, motor industrial vehicles, compaction machinery, road machinery, piling machinery, concrete machinery, steel processing machinery, decoration machinery, drilling machinery, other special construction machinery.

Casting is one of the basic technologies of modern machinery manufacturing industry. Casting as a metal hot processing technology, casting machinery is to use this technology to melt metal into liquid meet certain requirements and poured into the casting mold, after cooling, solidification, cleaning treatment to get a predetermined shape, size and performance of the casting can be used all the machinery and equipment, also known as casting equipment.

1. Testing standard (part)

Safety evaluation and inspection contents of foundry machinery

◇ Foundry machinery requires a solid foundation without cracks, anchor bolts fastened without loosening, firm and reliable.
◇ The whole equipment (set) pipeline has good sealing performance, no obvious oil leakage, air leakage phenomenon.
◇ Protective device is safe and reliable. The exposed transmission part of casting machinery is not only equipped with protection according to the general equipment, but also requires a protection device to prevent the diffusion of volatile raw materials and an apron-type metal baffle to prevent the fall of molding sand and objects. All the protection devices should reflect the effectiveness.
◇ The control system is clear and sensitive. The installation position of the control system is reasonable, easy to operate and maintain. At the same time, the various instruments, indicators and operation buttons in the system are reasonable, clear, clear and visible, sensitive and effective.

◇ Dust removal facilities are in good condition and effective. Each set of equipment must be equipped with dust and toxic and harmful gas removal facilities, and the requirements are intact and effective.
◇ Electrical interlocking of protective cover door: In the closed production process, in addition to a good sealing protection, the protective cover door is also required to install an electrical interlocking device.
◇ The size of the sand sample door is reasonable. In the closed production process, it is required to have a special sampling door at the appropriate position of the equipment, and the size of the sampling door is reasonable to ensure that the hand can not reach into the machine.
◇ Cardiac PE is reliable.

The standards applicable to mechanical products are generally divided into the following categories:

Class A standards (Basic safety standards)
It is mainly about basic concepts, design principles and general requirements applicable to all machinery.
Class B standards (safety standards)

are mainly used to deal with a safety situation or a related safety facilities, which can be widely used in a variety of machinery;
Class B1 standards for specific safety conditions (e.g., safe distance, surface temperature, noise)

The B2 standard is for relevant safety facilities (e.g., two-hand controls, interlocking devices, pressure sensing devices, shields).
Class C standards (Machine safety standards)

are mainly used for the detailed safety requirements of a particular type or class of machines.
Class C standard has the highest authority among these three standards, that is, if the same machine adopts class A, B and C standards at the same time, the requirements of class C standard have the highest priority. Class C standards are usually also called product standards. For example, EN201- Safety Requirements for Injection Molding Machines, which provides detailed and specific requirements for all possible risks of injection molding machines, basically including or referring to the requirements of class A and class B standards related to this type of products.

The most commonly used A, B and C standards for mechanical products are:
Class A standard: ENISO12100: Basic design Principles for Mechanical safety - Risk assessment and risk mitigation; .
Class B standard: ENISO13857: Safety of machinery - safe distance to prevent extension of upper and lower limbs and hazardous areas;
ENISO4413: Hydraulic systems - General requirements and safety specifications for hydraulic systems and hydraulic components;
ENISO4414: Pneumatic systems - General requirements and safety specifications for hydraulic systems and hydraulic components
EN1088: Safety of machinery - Interlocking devices mounted on shields - General principles of design and methods of selection;
EN953: Safety of machinery - General requirements for the design and construction of stationary and mobile shields;
En60204-1: Safety of machinery - Mechanical electrical equipment - Part 1: General requirements.

Class C standard :EN201: Plastics and rubber machinery - Safety requirements for injection molding machines
En415-1: Safety of packaging machinery - Part 1: Terminology and classification of packaging machinery and related equipment;
En415-5: Safety of packaging machinery - Part 5: balers;
En474-1: Earth-moving machinery - Basic safety requirements
EN692: Machine tools - Safety of mechanical presses;
EN693: Machine tools - Safety of hydraulic presses;
EN860: Woodworking machinery - Single plane;
EN869: Safety of machinery - Metal die casting machines;
EN1493: Automotive lifter;
EN12417: Machine tools - Safety requirements for machining centres;
EN12717: Safety of machine tools - Drilling press;
