A transparent look at our 6-stage manufacturing process — built on strict quality protocols, advanced machinery, and 20+ years of foundry expertise.
From premium raw material sourcing to verified product dispatch — every step is controlled for consistency and quality.
We source premium-grade silica sand with verified AFS grain fineness numbers, phenolic resins from certified suppliers, and additives that meet strict industry standards before any batch enters production.
Sand grains are heated and precisely coated with phenolic resin in a controlled hot-coat process. Temperature, resin ratio, and mixing time are all computer-monitored to achieve uniform coating thickness and optimal bond strength.
Coated sand is transferred into heated metal dies (tooling) at 230–270°C, where it cures in 15–60 seconds to form precision shell cores. Shell thickness is controlled to ±1 mm for repeatable dimensional accuracy every batch.
Shell moulds are produced in split halves using matched metal patterns, then bonded with a high-strength adhesive. Permeability and hardness tests are run on each mould set to ensure casting reliability across ferrous and non-ferrous alloys.
Every finished batch undergoes a multi-point quality inspection before approval for dispatch. Dimensional, tensile, and visual checks are performed. Non-conforming products are segregated and recycled, never shipped.
Approved products are carefully packed in customized corrugated packaging with anti-moisture liners. Each shipment is labelled with batch number, product spec, and date of manufacture. We offer Pan-India logistics with reliable third-party freight partners.
Multi-stage testing at every production milestone ensures consistent, specification-grade products in every batch.
Every batch is tested on a calibrated tensile testing machine. Minimum thresholds are enforced before any product is approved for dispatch.
Incoming sand and outgoing coated sand batches are both sieve-tested to confirm grain fineness is within the specified AFS range for each product grade.
Shell cores and moulds are measured with calibrated vernier calipers and go/no-go gauges to verify critical dimensions before release.
Gas evolution during casting is a critical parameter. We test each resin grade batch to ensure low-gas output, preventing porosity defects in the final casting.
Shell core halves are manually peel-tested to ensure adequate bond strength at the parting line, preventing core break during mould assembly.
All finished products undergo trained operator visual inspection for cracks, inclusions, surface pitting, and parting-line flash before packaging.
We are committed to achieving and maintaining industry-recognized quality certifications. Certification details will be updated as obtained.
