DimensionsCustmer's DrawingsServiceOEM ODM Customised
Large scale heavy steel sand castings are offered for mining and construction machinery. OEM and ODM enquiries follow customer drawings, with galvanizing as the listed surface treatment. Define the component and its working duty so the casting request is tied to the actual equipment configuration.
Explain the machinery load path
Show where the steel casting connects to the machine and which interfaces transmit its working loads. Include the installation orientation, mating components and operating environment. For replacement enquiries, distinguish the intended design from wear on the existing part. These details help establish the requirements that the selected steel and finished geometry must satisfy.
Control dimensions through the drawing
Identify the governing steel grade, drawing revision and dimensional limits. Large castings may contain several relationships that must be assessed together, so specify the datums used to evaluate those interfaces. If the component needs machining, heat treatment or a particular test method, include that requirement in the quotation brief for agreement.
Specify galvanizing and acceptance
Describe the galvanized finish required for the part and identify any functional surfaces whose final condition affects assembly. Connect finish acceptance to the relevant drawing areas. ISO 9001:2015 is the quality reference; confirm the applicable document and scope when agreeing the order.
An effective mining or construction machinery enquiry also states the required quantity, part approval process and records needed with the finished castings. Agree how deviations will be assessed before production. Keep approved changes linked to the same drawing revision and machinery duty, so repeat enquiries refer to the same component rather than a broad heavy-casting category.
