Compliance overview
Scope and applicability
This standard specifies the basic safety technical requirements for the design, manufacturing, and usage of low pressure die casting machines. It applies specifically to machines with crucible sealing and furnace body sealing, including both horizontal and vertical parting types. It is mandatory for manufacturers and suppliers of these specific casting machines to comply with this standard. Note that Chapter 3 is recommended, while all other chapters are mandatory.
Technical requirements
The standard outlines comprehensive safety measures to mitigate mechanical hazards such as crushing, shearing, and impact from moving parts. It mandates specific protective devices for the mold danger zone, including interlocking systems for mold closing and pouring operations. Manufacturers must ensure that mold closing and pouring are strictly interlocked to prevent accidental ejection of molten metal. For high-pressure fluid systems, the standard requires compliance with general technical conditions for hydraulic and pneumatic systems to prevent explosion or leakage hazards. Electrical systems must adhere to relevant machinery electrical equipment standards, with specific provisions for high-temperature environments and cable shielding. The standard also references GB 5226.1 for electrical equipment safety. The document addresses thermal hazards by requiring reliable sealing between the holding furnace and the mold, along with strict interlocking mechanisms to prevent opening under residual pressure. Noise limits are specified to protect operators from hearing loss, and requirements for ergonomic design and electromagnetic compatibility are also included. Operators must be protected from smoke, oil mist, and potential fire risks associated with hydraulic fluids and mold coatings.
Testing methods
Compliance with the safety requirements is determined through a prioritized sequence of four verification methods. Functional testing is the primary method to verify the performance of specified safety components. If not feasible, instrumental detection is used to check if parameters are within limits. Further verification can be conducted through calculations and drawing reviews for structural stability, or finally, through visual observation to ensure required safety performance and proper usage information are present.
