Any supplier can claim "factory price". The only question worth asking is who machines the parts that carry the load. Here is what we do in-house, and how you can check it yourself.
In this industry the word is used loosely. Some companies design and assemble but buy their castings, their machined parts and sometimes their finished machines. Others machine the critical components themselves and control the whole chain from raw part to tested machine. The difference only becomes visible when something goes wrong — or when you ask to see the machining area.
We machine the load path: main frames, eccentric shafts, gear pairs and bowl assemblies. We heat-treat and non-destructively test critical components. We fabricate the structure and conveyors that go between the machines. And we assemble and run-test every crusher before it leaves.

Machining capability parameters — maximum machining diameter and maximum single-part weight — are being verified with the production department and will be published here once confirmed. Ask us in the meantime and we will get the figures from the works for your specific part.
Because machining is not queued behind an outside supplier's order book, standard machine lead time stays at 60 days from order confirmation.
A casting or machining defect found before assembly is a workshop problem. The same defect found on your site is a shipping, customs and downtime problem.
Wear and spare parts come off the same drawings and the same machines. We supply within two months worst case, typically far faster for running models.
Material certificates, inspection records and the machine's serial-numbered test report come out of a factory quality system, not assembled afterwards.
We would rather be checked than believed. Three things will do it:
Visit Hangzhou, Weihai or Wuhu — bring your inspector. Or ask for a live video walk-through of the machining area and assembly floor.
Ask any supplier which components are machined in-house and which are bought in. The answer tells you more than a factory tour.
Request a sample factory test report and see whether it is serial-numbered, specific and tied to a packing list — or a generic template.
Pick one critical component — an eccentric shaft, a bowl assembly — and ask where it was made and how it was tested. We will answer with the works and the process.
Tell us the component and the requirement. We will confirm from the works whether it is machined in-house, on what equipment, and with what inspection record — the answer is usually more useful than a factory tour.
