With abundant experience, we are committed to providing high quality customized service and OEM service to global clients. Welcome to buy advanced vertical shaft impactor upper frame assembly made in China here from our factory. Contact us for quotation.
Overview
Every VSI crusher relies on its top-mounted frame to control how feed material enters the rotor chamber. The Vertical Shaft Impactor Upper Frame Assembly combines the outer shell, internal storage tank, feed gate mechanism, and bypass liner system into a single structural unit - positioned directly above the crushing chamber on machines such as the MP VSI4000.
Because this frame absorbs constant material flow and vibration during operation, procurement teams typically replace it as a complete assembly once the shell or internal liners reach end-of-life, rather than sourcing individual sub-parts separately. We produce this assembly to original specifications and support custom builds for equivalent vertical shaft impactor platforms.
What Sets Our Manufacturing Apart
Reverse Engineering from Worn Samples
No drawing available? Send the damaged frame and our team rebuilds the 2D/3D model, with a reference drawing typically ready in ~3 days.
Alloy Matched to Wear Conditions
High manganese steel for high-impact feed, chromium-molybdenum alloy for abrasive high-tonnage duty - selected per your operating profile rather than supplied generically.
Verified Material & Dimensional Accuracy
Spectral composition analysis, HRC hardness testing, and CMM dimensional inspection confirm each batch before shipment; third-party inspection available on request.
Direct Factory Pricing
Manufactured in-house in Quzhou, China, with no trading-company markup.
5-Unit MOQ
Enables single-unit trial orders before committing to fleet-level stock.
Export Packaging & OEM Branding
Fumigated wooden crates or steel-frame packaging for ocean freight; laser logo marking available for private-label buyers.

Frequently Asked Questions
1. How do I tell if my current frame needs replacing?
Visible cracking in the shell, a feed gate that no longer closes flush, or bypass liners worn through to the backing plate are the usual signs it's time to replace the full assembly.
2. I only have a broken part, not a drawing - can you still quote this?
Yes. Send the physical piece or detailed photos with measurements, and our team will reconstruct the design before quoting.
3. Will this work on a brand other than MP?
Possibly - send your model details or a sample for us to confirm before ordering, since dimensions vary between manufacturers.
4. Why does material choice matter for this part?
The frame experiences different stress types depending on your ore - abrasive material wears alloy steel down over time, while high-impact feed favors manganese steel's work-hardening properties. Choosing the wrong grade shortens service life.
5. What's a realistic timeline from order to shipment?
Budget 15–30 days for production; some standard components may ship faster if already in stock.
6. Can you provide test reports with the shipment?
Yes, hardness and dimensional inspection results are available, and third-party inspection can be scheduled if your company requires it for import clearance.
7. Is there a small-order option for first-time buyers?
Yes, orders start at 5 units, so you can test one unit before placing a larger repeat order.
8. Do you brand parts under our company name?
We support laser logo engraving on request, along with export packaging suited to your shipping route.
9. What's covered if the part is faulty on arrival?
Verified manufacturing defects are replaced at no cost, with responsive support throughout the claims process.
10. Which shipping arrangements do you offer?
Exports move under FOB or CIF terms from Shanghai or Ningbo, and we can coordinate with your freight forwarder of choice.
