What We Solve
Production Challenges We Help You Overcome
Real problems faced by mining, quarry and aggregate operators — and how our castings solve them.
Wear parts wear out too fast, crushing stops every week
High manganese steel and high chrome alloy iron castings are heat-treated to extend service life, so your crusher runs longer between change-outs.
OEM spare parts are too expensive
Direct-from-foundry pricing on equivalent mantles, concaves, jaw plates and hammers. Same dimensions, foundry-direct cost savings.
Long lead times delay production
In-house pattern making, melting, heat treatment and machining keep our typical lead time at 30 to 45 dienos, faster than most OEMs.
Generic parts don't fit, quality varies between batches
Each casting follows your drawing or OEM spec, with chemical composition and hardness reports on every batch for consistent quality.

FAQ
Questions Customers Usually Ask
Honest answers about materials, lead times and shipping.
Are your parts OEM equivalent to Sandvik, Metso or Trio?
Yes. We manufacture wear parts equivalent to major OEM brands according to customer drawings or samples. Our mantles, concaves, jaw plates and other castings are made to the required dimensions and material specifications, with full chemical and hardness reports available.
What materials do you use for crusher wear parts?
We cast high manganese steel (Mn13, Mn18, Mn22, Mn13Cr2, Mn18Cr2), high chrome alloy iron (Cr15, Cr20, Cr26) and carbon or low-alloy cast steel depending on the application. The grade is selected against the wear mechanism — impact-dominant duty and abrasion-dominant duty need different materials — and we recommend the grade based on your feed material, trupintuvo nustatymas ir veikimo sąlygos.
What is your typical lead time?
For standard parts, our typical lead time is 30 to 45 days from order confirmation. Custom castings may take 45 to 60 days depending on complexity. We can also keep stock of common parts for faster delivery on repeat orders.
Can you make custom castings from my drawing?
Yes. Send us your 2D or 3D drawing and we will quote with material grade, weight, price and lead time. Our in-house pattern shop can produce new patterns from your drawings within 2 to 3 weeks.
How do you ship heavy castings overseas?
We pack castings in seaworthy wooden cases with steel frame reinforcement and waterproof film. For bulk orders we use break-bulk or container shipping, with all export documentation handled by our logistics team.
What quality certificates do you provide?
We are ISO 9001 certified. Every batch comes with material certificate, chemical composition report, mechanical property report (tensile, derlius ir poveikis), hardness record and dimensional inspection report. Third-party inspection (SGS, BV, Intertek) is available on request.
