Design Review and Finalization

Evaluating design files in depth from manufacturing feasibility and cost optimization perspectives.
  • Design for manufacturing (DfM) refinements to improve producibility.
  • Material grade recommendations based on mechanical performance needs.
  • Optimal manufacturing process selection viz. sand casting, investment casting etc.
  • Preliminary quotations for different material and process combinations to align with budget.
  • This collaborative approach enables finalizing an optimal design tailored to your functional needs and product goals early in the development cycle.

Rapid Concept Validation through Prototyping

Developing working prototypes swiftly based on finalized parameters for design validation.

With the drawings and specifications frozen, our team swiftly produces 1-2 functional prototypes usually within 3-4 weeks. You can then thoroughly evaluate these prototypes from dimensions, visual appearance, performance factors and compliance to industry standards perspectives.

We allow 2-3 iterations incorporating your feedback to fine-tune the design till you finalize a configuration meeting all criteria. This validation through working models reduces downstream changes after full-scale production.

Streamlined Volume Manufacturing

Efficient production batch execution as per the finalized specifications.

Utilizing final drawings and parameters, our production team is able to produce 2000-5000 sets of products in 20-30 days depending on complexity, order quantity and finishing requirements. We use sand casting, die casting and other appropriate techniques based on product specifications to achieve the best quality and cost balance.

Our real-time quality monitoring at each manufacturing stage ensures adherence to material grade, target dimensions within specified tolerances, requisite surface finish and functional performance. Continuous client involvement allows swift issue resolution during execution.

Validation and Delivery

Multi-level verification prior to customer dispatch.

Before shipment, finished products undergo thorough verification spanning:

  • Dimensional inspection using CMMs and optical systems to validate conformance to drawings.
  • Visual examination for defects and blemishes.
  • Functional testing against expected mechanical performance.
  • We also obtain your approval of product samples from the dispatched batch. Once you validate the quality, products are securely packed and swiftly shipped to your desired location through inland or sea transportation.

Metalworking Equipment for Diverse Applications

Our extensive machinery portfolio enables manufacturing small batches of intricate prototypes to volume production of large metal parts for varied construction needs.

Optimal Materials to Withstand Demanding Conditions

We select and source suitable metal alloys that stand up to heavy usage requirements while meeting performance needs cost-effectively.

  • Austenitic and Duplex Stainless Steels

    We fabricate components using corrosion-resistant stainless steels like 304, 316 and duplex grades for applications involving water, chemicals and outdoor environment exposure. The austenitic structure ensures good ductility and weldability besides corrosion resistance.

    We also offer super austenitic grades like 904L and 254SMO along with equal/unequal leg angle sections as per design needs. Based on service conditions, we provide different surface finish options like pickling, passivation, electro-polishing etc. to further enhance corrosion protection.

  • Cast and Wrought Aluminum/Zinc Alloys

    Lightweight aluminum/zinc alloys ensure material savings. We produce aluminum parts using grades like LM25, LM6, AlSi9Cu3 etc. having excellent casting characteristics plus ability to be strengthened through heat treatment. For structural components needing good fatigue resistance, we offer A356-T6, 2618-T61 grades that can match performance levels of some steels.

    High-precision, thin wall zinc alloy parts are made using ZA alloys on our fully automated hot chamber die casting machines. We provide complete finishing operations like CNC machining, drilling, tapping, reaming, grinding etc. for aluminum and zinc castings.

Enhancing Durability, Appearance and Performance

We offer a variety of surface treatments to improve corrosion & wear resistance, aesthetics, functionality etc. as per operating conditions.

Anodizing Anodizing creates a thick oxide layer on aluminum components, enhancing corrosion & abrasion resistance. Different anodizing types suit different environments.
Powder Coating We apply durable and attractive powder coatings to metal parts after suitable pre-treatment. This improves aesthetic appeal and protects against corrosion.
Electroplating Electroplating deposits a metallic coating like zinc, nickel, chrome etc. onto metal components to enhance specific properties.
Phosphating Phosphating applies protective phosphate coatings on metal components, acting as an excellent paint base besides improving wear resistance.
Passivation We provide passivation (oxide layer formation) surface treatment for stainless steel components, boosting corrosion resistance.
Sand Blasting Our sand blasting process smoothens surfaces and facilitates painting by creating an anchor pattern through controlled abrasion.
