Pattern Shop Operations
At Periyar Crusher Machines Pvt. Ltd., our dedicated pattern shop is the foundation of our casting precision. Patterns are the blueprint of every casting, and we design them with exactness to ensure consistency, dimensional accuracy, and smooth surface finishes in the final components.
Our in-house team uses both traditional woodworking and modern modeling techniques to develop patterns that suit a wide range of casting materials and shapes—from simple machine parts to intricate crusher components.
- Material selection (wood, aluminum, resin)
- Shrinkage allowance and machining margins
- Complexity and size of the casting
Step-by-Step Pattern Making Process
Pattern Design and Modeling
Our pattern-making process starts with the creation of detailed 2D and 3D CAD models that precisely represent the final casting’s geometry.
- Engineers carefully design patterns considering crucial factors such as mold flow dynamics, material shrinkage, machining allowances, and parting line placement.
- This digital modeling phase is essential to optimize pattern efficiency, ensure consistency, and guarantee seamless compatibility with subsequent mold-making operations.
- By addressing these parameters early, we minimize risks of defects and improve the overall quality of the final castings.
Pattern Fabrication and Assembly
Once the design is approved, skilled technicians bring the digital models to life:
- Patterns are fabricated using a combination of CNC machining for precision shaping and manual finishing for fine detail work.
- For complex components, we create split patterns, match plates, and core boxes that facilitate mold assembly and core placement.
- All patterns are reinforced to withstand repeated use in production cycles and incorporate precision alignment features to ensure consistent assembly accuracy in multi-part molds.
Testing and Validation
Before moving to full-scale casting, every pattern undergoes rigorous testing:
- We check dimensional accuracy and surface quality to ensure the pattern meets design specifications exactly.
- This validation step helps identify and correct potential issues that could lead to casting defects, such as misalignments or surface irregularities.
- Patterns are also inspected for durability and reusability, with quality controls confirming compliance with tolerance standards essential for long-term production reliability.
