Duma has successfully completed a two-container export shipment of jaw plates to a customer in the United Kingdom. The goods were dispatched from Duma's own manufacturing facility with a complete set of export documentation, ensuring smooth customs clearance and timely delivery at the destination port.

This shipment is a straightforward reflection of what Duma does on a consistent basis: producing heavy-duty crusher wear parts in bulk, to a verified quality standard, and delivering them to mining and quarrying operations around the world on schedule. For this particular UK customer, Duma supplied a batch of jaw plates manufactured from high-manganese steel, processed through Duma's full in-house production chain and inspected to export standard before loading.
Every jaw crusher part that leaves Duma's factory is produced entirely within the company's own 42,000 m² integrated facility. Duma operates as a direct manufacturer, not a trading company, which means complete control over every stage of production: raw material inspection, high-manganese steel smelting and casting, computer-controlled water toughening heat treatment, precision machining, and final quality inspection. There are no outsourced processes involved - full traceability is maintained from the first pour to the finished part.
On the materials side, Duma's jaw plates are available in high-manganese steel grades including Mn13, Mn18, and Mn22, selected according to the customer's ore type and crusher operating conditions. Following Duma's controlled water toughening process, parts leave the factory with an initial hardness of approximately HB200. Once placed into service and subjected to repeated impact, surface hardness increases rapidly to HB500 or above through work hardening, while the core of the casting retains its toughness. This balance of surface hardness and internal ductility prevents premature cracking and extends service life - typically 20% to 40% longer than standard replacement parts, translating into lower total maintenance costs for the end user.
Before any batch is approved for shipment, it goes through Duma's standard quality control procedure: hardness testing to verify heat treatment results, metallographic analysis under high-magnification microscopy to confirm a clean austenitic structure free of carbide precipitation, dimensional inspection to ensure precise fit against the customer's crusher frame, and ultrasonic non-destructive testing to detect any internal casting defects. Material certificates, heat treatment curves, dimensional reports, and metallographic reports are provided with every order and are fully traceable by batch number.
Partial Inspection Reports
Duma holds ISO 9001:2015 certification and backs every shipment with a 12-month warranty against casting defects. Flexible trade terms including FOB, CIF, and EXW are available, and Duma's in-house logistics team handles full export coordination from production scheduling through to vessel booking and documentation, ensuring orders depart and arrive on the agreed timeline.
With a pattern library of over 4,000 molds covering major crusher brands including Metso C-series (C80, C100, C125, C160 and more), Sandvik CJ and JM series, Terex, Powerscreen, and Kleemann, Duma is positioned to fulfill both standard and custom orders without lengthy tooling lead times. Standard in-stock items ship within 7–10 days; custom castings are typically completed within 30–45 days.
This UK shipment is one of many international export orders Duma fulfills each month, serving mining operators, quarry contractors, and wear parts distributors across Europe, Australia, South Africa, and beyond. As global demand for reliable, high-performance jaw crusher parts continues to grow, Duma remains committed to delivering consistent quality, stable lead times, and full technical support at every stage of the procurement process.
