Engineering Technologies

Growth’s full service offers cutting-edge technology for technical specialists to assess and optimise casting design and maximise product quality.
Feature Image

3D Laser Scanning

Growth implements change to advanced software and 3D laser scan technology that offers a continuous condition monitoring of installed liners in mills and accurately forecasts reline timing based on wear trend analysis. Mill scanning improves the liner inspection in terms of time and accuracy.
Feature Image

3D Liner Profiling

Growth analyses the scanned worn liner profiles recorded to enable those profiles to be optimized in terms of performance in wear life and grinding efficiency.
Feature Image

3D Dem Simulation

3D DEM is an engineering simulation tool that simulates particle behaviour within a conveyor chute, mill, or other materials handling system. In grinding mills, this software can be used to validate a recommended liner design under operational conditions, providing information on mill power draw, grinding effectiveness, and discharge end performance.
Feature Image

Computer Aided Design (CAD)

Creating a virtual representation of the final product to validate the form, fit and function of the product before they are built. All these product models are stored in our data management tool integrated with the CAD software, recording the history of the models, monitoring the progress as well as maintaining the version control in multi-user environments.
Feature Image

Cnc Pattern Manufacturing

Growth continually improves manufacturing capability and accuracy by change translating to utilising 3D CAD/CAM and CNC process to provide high quality products.
Feature Image

Casting Simulation Software

Casting simulation software uses Finite Difference Method calculations to simulate the thermal solidification of casting while Computational Fluid Dynamics simulates the fluid flow inside the cavity of the moulding sand. This software offers many advantages including the improvement of a casting’s quality, reduction of lead time, optimization of cost, ease of redesign and elimination of the potential casting defects prior to production.
