Quality
Where Quality is Crafted
Commitment to Customers
We work closely with our customers to understand their application requirements and quality expectations. Our goal is to supply castings that:
- Meet specified dimensions and tolerances
- Deliver consistent mechanical performance
- Arrive on time and ready for use
Ashokhans Casting LLP stands for reliability, precision, and excellence in sand casting.
Quality is not an act — it is our process.
Continuous Improvement
At Ashokhans Casting LLP, quality is continuously enhanced through:
- Process monitoring and corrective actions
- Root cause analysis of defects
- Skill development and operator training
- Feedback integration from customers
Our focus is to reduce rework, improve yield, and deliver consistent quality.
Tools & Equipment Supporting Quality
- Sand testing equipment
- Temperature measuring instruments
- Precision measuring tools (vernier calipers, gauges)
- Inspection fixtures and templates
- Surface inspection tools
These tools enable accurate process control and reliable inspection.
7. Inspection & Testing
Each casting undergoes systematic inspection:
- Visual inspection for surface defects
- Dimensional checks using gauges and measuring instruments
- Weight and thickness verification
- Application-specific checks (as required)
Only castings that meet acceptance criteria proceed to dispatch.
6. Cooling & Fettling
- Controlled cooling to prevent cracks and distortion
- Removal of gates, risers, and excess material
- Shot blasting or surface cleaning as required
This improves surface finish and prepares castings for inspection or machining.
5. Melting & Pouring Control
Metal melting and pouring are closely monitored.
- Controlled furnace temperature
- Clean metal handling and slag removal
- Temperature measurement before pouring
- Steady and safe pouring techniques
Correct pouring temperature and method ensure sound internal structure and reduce porosity.
4. Molding & Core Making
- Proper compaction and mold stability
- Accurate core positioning for internal cavities
- Inspection of molds and cores before pouring
This stage ensures correct shape formation and internal geometry.
3. Sand Preparation & Testing
Molding sand quality directly affects surface finish and strength.
- Controlled sand mixing ratios
- Moisture content testing
- Permeability and strength testing
- Reclamation and reuse under controlled conditions
Proper sand control minimizes defects such as blow holes, sand drop, and erosion.
2. Pattern & Tooling Accuracy
Accurate patterns are critical for dimensional precision.
- Precision pattern making and maintenance
- Allowances for shrinkage and machining
- Regular pattern inspection for wear and damage
This step ensures repeatability and dimensional consistency across batches.
1. Raw Material Inspection
Quality begins with the right inputs.
- Selection of approved metal grades and alloys
- Visual inspection of scrap and raw materials
- Control over chemical composition (as per application requirements)
This ensures uniform metallurgical properties in the final casting.
Quality Control Process in Sand Casting
- Quality is built into the process, not inspected at the end
- Consistency through standardized operating procedures
- Continuous improvement through process monitoring and feedback
- Commitment to customer specifications and application needs
Our Quality Philosophy
At Ashokhans Casting LLP, quality is the foundation of everything we manufacture. Our sand casting operations are driven by controlled processes, skilled workmanship, and systematic inspections to ensure every casting meets dimensional accuracy, strength, and performance requirements.
We follow a process-driven quality approach — from raw material selection to final inspection — to consistently deliver reliable and defect-free castings
