What Are OEM Crusher Parts?
OEM crusher parts refer to wear components manufactured to the exact dimensional tolerances, material specifications, and performance standards of the original equipment manufacturer. Whether you operate Metso, Sandvik, Terex, Powerscreen, Kleemann, Telsmith, or Trio crushers, your equipment demands replacement parts that fit perfectly, perform reliably, and last as long as - or longer than - the originals.
At Jiangxi Duma Machinery Manufacturing Co., Ltd., we have spent over 15 years perfecting this discipline. We are not a trading company. We are a direct factory: every OEM crusher part we supply is designed, cast, heat-treated, machined, and tested under one roof, across our 47,000 m² manufacturing facility in Jiangxi Province, China.
Our OEM Manufacturing Capabilities
Drawing-Based & Reverse-Engineering Production
Duma supports OEM production via two pathways:
From Original Drawings
Submit your technical drawings or CAD files, and our engineering team will follow your exact dimensional tolerances and alloy specifications. We strictly adhere to all OEM fit accuracy requirements, ensuring your replacement part installs without modification.
From Worn Samples (Reverse Engineering)
If original drawings are unavailable, our engineers perform precise 3D measurement and data mapping on worn samples. We reconstruct the original geometry, identify high-wear zones, and where appropriate, recommend profile or alloy optimizations to extend service life beyond the OEM baseline.
4,000+ Mould Library - Your Model, Ready to Cast
One of Duma's most significant OEM production advantages is our library of over 4,000 patterns and moulds, covering the world's most widely deployed crusher models. For the vast majority of Metso, Sandvik, and other major-brand machines, there is no tooling lead time - we cast directly from existing patterns, which dramatically compresses your delivery schedule.
Crusher brands and models we routinely supply OEM-equivalent parts for include
- Metso / Nordberg: C Series jaw crushers (C80, C100, C105, C125, C140, C160, C200), HP Series cone crushers (HP100, HP200, HP300, HP400, HP500, HP800), GP Series cone crushers
- Sandvik: CJ Series jaw crushers (CJ411, CJ412, CJ511, CJ615, CJ815), JM Series, CH/CS Series cone crushers
- Terex / Powerscreen / Pegson: jaw and cone models across the full range
- Kleemann, Telsmith, Trio, and other global OEM brands
Materials & Metallurgy: Meeting and Exceeding OEM Standards
Duma's OEM crusher parts are manufactured from premium alloys engineered to deliver consistent, predictable performance in demanding applications:
High Manganese Steel (Mn13, Mn18, Mn22)
Our core material for jaw plates, mantles, concaves, and bowl liners. Controlled solution heat treatment - executed in our computer-controlled furnaces using a step-by-step temperature rise protocol - develops the single-phase austenite microstructure that defines true work-hardening performance. Surface hardness rises from approximately HB 200 at installation to HB 500+ under impact, providing progressive wear resistance that protects your machine frame.
Alloy Upgrade Grades
For highly abrasive or high-impact applications, we offer customised alloy compositions including Cr-Mo modifications and Titanium Carbide (TiC) ceramic insert composites, delivering up to 30–40% longer service life compared to standard Mn13.
Every heat treatment batch is documented
furnace curves, metallographic reports, hardness results, and dimensional inspection records are archived for full batch traceability. All material grades are produced in compliance with ASTM A128 or GB/T 13932.
Quality Control: Verified to OEM Tolerances
Delivering a part that fits, functions, and lasts requires more than the right alloy. Duma applies a rigorous multi-stage inspection process before any OEM part ships:
Spectral Analysis (German SPECTRO Spectrometer)
Chemical composition is verified before and after every melt to confirm alloy accuracy.
01
Metallographic Testing
High-magnification microscopy and image analysis software confirm a clean austenite matrix with no network carbide precipitation - the critical factor that distinguishes a part that work-hardens from one that fractures.
02
Hardness Testing
Every batch is hardness-checked to verify proper water-toughening (quenching) results.
03
Dimensional Inspection
Strict CMM and manual gauging ensures all critical dimensions - mounting surfaces, locating faces, and profile geometry - match OEM specifications within tolerance.
04
Non-Destructive Testing (NDT)
Ultrasonic Testing (UT) and Magnetic Particle Testing (MT) are available for large or safety-critical castings, and Penetrant Testing (PT) is offered as required.
05
The result: parts that install cleanly with no field grinding, and run predictably from day one.
Stocking & Lead Times
Duma maintains large in-stock inventory of the most commonly consumed OEM-equivalent wear parts for Metso C Series jaw plates and HP/GP cone liners, Sandvik CJ and CH/CS series parts, and other high-volume models. Standard in-stock parts ship within 7–10 business days.
For custom or non-standard profiles, typical production lead time is 30–45 days, supported by our full in-house casting, heat treatment, and machining workflow - no subcontracting, no quality gaps.
OEM Supply for Distributors & Mining Operations
Whether you are a crusher OEM distributor building an aftermarket parts program, a mine operator managing planned maintenance schedules, or a dealer serving multiple machine brands, Duma is structured to support you:
- Flexible MOQ: We accept trial orders for quality verification, and scale to full volume supply without minimum commitment hurdles.
- Competitive Factory-Direct Pricing: As a direct manufacturer with no intermediaries, our pricing reflects true factory cost - not a trading company markup.
- Private Label & OEM Branding: Available upon request for qualified distribution partners.
- Export Documentation: Full technical packages including material certificates, heat treatment records, dimensional inspection reports, and all export clearance documents are provided as standard.
- Shipping Terms: FOB, CIF, and EXW all supported; we coordinate international logistics to mining sites across Australia, Africa, North America, South America, and Southeast Asia.
