HPML Pattern Making

High-precision match plates and patterns for all major moulding lines

We manufacture precision HPML patterns for all major high-pressure moulding lines — DISA, SINTO, KOYO, ARPA, DARPA and SARVAMANGALA. Our VMC-machined match plates deliver consistent casting quality with minimal rejection rates across high-volume production runs.

About This Service

High Pressure Moulding Line (HPML) patterns are the foundation of modern, high-speed foundry production. Unlike traditional hand-moulded patterns, HPML patterns must withstand thousands of sand squeezes at pressures up to 150 bar while maintaining dimensional stability. A poorly made HPML pattern causes sand erosion, mis-runs, and dimensional scatter across every casting produced from it.

At Super Innovation, we have been making HPML patterns since 1999 — over 25 years of refining our shrinkage calculations, draft angle selection, runner system design, and ejector pin layout for each moulding line we serve. We use CAD/CAM to design every pattern from your 2D drawing or 3D model, machine it on our BT40 VMC fleet to ±0.005mm accuracy, and support you through the first casting trial until approval is achieved.

What's Included

Single, dual and multi-cavity match plate designs
Accurate shrinkage allowances per alloy grade
Proper draft angles and fillets for clean sand release
Balanced runner, gate and riser systems
CAD/CAM designed from 2D drawings or 3D models
COPE & DRAG patterns with dowel alignment
Weldable inserts for high-wear zones
Reverse engineering from worn patterns or castings
First trial support — modifications included

Our Process

01

Drawing Review & Feasibility

We review your 2D drawing or 3D model, assess moulding line compatibility, identify parting line, draft angles, and flag any casting design issues. Feedback within 24 hours.

02

CAD Modelling & Shrinkage Calculation

Our engineers build a full 3D CAD model, apply alloy-specific shrinkage allowances, design the runner/gating system, and add ejector pin bosses per your moulding line specification.

03

CAM Programming & VMC Machining

CAM toolpaths are generated and transferred via DNC to the appropriate VMC machine. Patterns are rough-machined, semi-finished, and finish-machined in sequence for maximum accuracy.

04

Inspection & Dispatch

Complete dimensional inspection on all critical surfaces. Pattern mounted on backing plate, alignment checked. Dispatch with inspection report and CAD file.

05

Trial Support

We support the first foundry trial remotely or on-site. If gating corrections, shrinkage adjustments or ejector modifications are needed, we turn them around quickly.

Frequently Asked Questions

DISA vertical line (like DISA 240/280) uses a vertically parted flaskless moulding process — the pattern is a match plate with cope and drag on opposite faces. DISA horizontal uses a horizontally parted flask system, similar to SINTO and KOYO. We manufacture both types and understand the sand pressure, ejection force and dimensional requirements unique to each.
