Jaw Crusher Front Frame – Custom Cast & Machined Structural Casting
Direct-fit for PEV130-series and Metso/Sandvik/Terex/Trio-type jaw crushers | Built to drawing, part number, or worn sample
What a Crusher Front Frame Does
In a jaw crusher, the front frame is the load-bearing half-shell that the fixed jaw, cheek plates, and pitman assembly all bolt into. Every crushing stroke pushes reaction force from the toggle plate and eccentric shaft back into this casting, so its wall thickness, rib layout, and bolt-hole spacing directly determine how long the machine runs between shutdowns. When a front frame is undersized, poorly heat-treated, or cast with the wrong alloy, operators typically see the same failure sequence: cheek plate bolts working loose, hairline cracking around the toggle seat mounting, and eventually a frame that no longer holds tolerance for the jaw plates - at which point patch-welding is a temporary fix at best.
How We Engineer Front Frame Replacements
Rather than treat the front frame as a generic casting, our production process is built around matching it to two things: the customer's original machine tolerances, and the ore/material conditions it will run against.
Dimensional accuracy
We work from the customer's original part drawing or part number where available. Where no drawing exists - a common situation for older or modified machines - our technical team measures the worn or damaged front frame directly and rebuilds it as a new 2D/3D model, typically returning a first draft drawing within about 3 days.
Alloy selection
Standard front frame builds use high-manganese steel or chrome-molybdenum alloy steel; for sites running unusually abrasive or high-impact ore, our lab can adjust the alloy ratio and run bimetal composite or additional quenching passes to extend service intervals without changing the frame's external footprint or bolt pattern.
Interface compatibility
Every front frame is machined so cheek plate liners, side plates, and toggle seat holder mounts bolt on using the same fastener spacing as the original equipment - the goal is a frame that drops into an existing assembly without re-drilling or shimming.
Production & Inspection Workflow
Customer supplies part number, drawing, or a worn sample for measurement
Alloy grade confirmed against operating conditions (ore hardness, feed size, impact load)
Precision casting and CNC machining to tolerance
Heat treatment / quenching for wear resistance
QC pass: raw material spectral test, HRC hardness check, three-coordinate dimensional inspection, flaw detection, optional third-party sign-off
Export packaging (fumigated wood crate or steel frame) and shipment
Typical lead time runs 15–30 days after drawing/spec confirmation, with a minimum order of 5 pieces. Common front frame sizes are kept in stock for faster turnaround.
About the Factory Behind This Part
This front frame line is produced by Quzhou Horbon Mining Parts Co., Ltd., a factory-direct manufacturer in Quzhou, Zhejiang (established 2025, ~13,000 m² plant). The team runs its own casting/melting and machining operations rather than trading through a third party, which is what allows custom alloy work and reverse-engineering to happen on the same production line as standard replacement parts.
Beyond front frames, the same facility supplies the fuller crusher wear-and-structural range - cheek plates, main shafts, rotor assemblies, bushings, springs, and fasteners - so a front frame order can be paired with matching liners and hardware in one shipment. Export shipments go out FOB or CIF from Shanghai or Ningbo, and the company has supplied 50–200 overseas customers across Southeast Asia, the Middle East, Africa, Europe, the Americas, South Asia, and Australia, with 24/7 technical response and free replacement in confirmed quality cases.
Common Questions
Q: Can you build a front frame without an original drawing?
A: Yes - send photos and key measurements of the worn part, or ship us the sample. We measure and reverse-engineer a 3D model before quoting.
Q: Which crusher models does this fit?
A: Confirmed compatibility with PEV130-series jaw crushers; comparable frames for Metso, Sandvik, Terex, Trio, and generic domestic jaw crushers can be built against your part number.
Q: Can the alloy be changed for harder ore?
A: Yes - alloy ratio and heat treatment are adjustable per order based on the site's actual wear conditions
