Non-Ferrous Castings: Aluminium, Brass & Copper
Aluminium castings dominate the non-ferrous side of the foundry business, but brass and copper still have their place for specific applications. This guide compares aluminium castings against brass and copper, covers where each is used, and explains the casting and machining considerations for non-ferrous metals. The popularity of aluminium castings comes down to a simple […]
Ferrous Castings: Cast Iron, SG Iron & Steel
Cast iron and SG iron castings cover most of what a heavy engineering or automotive buyer needs from a ferrous foundry — but the two materials behave very differently under load. This guide compares cast iron and SG iron castings against steel, covers where each material is used, and explains how quality is verified. Getting […]
Investment Casting: Precision Parts with Superior Finish
Investment casting is the process to reach for when a part needs complex geometry, fine detail, and a surface finish that other casting methods simply can’t match as-cast. This guide covers how investment casting works, when it’s the right choice, its role in aerospace-grade work, and how a part moves from design through to delivery. […]
Pressure & Low Pressure Die Casting: Thin Walls and HighVolume
When a part needs thin walls, fine detail and very high volume, pressure die casting is usually the answer. This guide covers how pressure die casting works, how low pressure die casting differs, the benefits for your part, and the design considerations that affect tooling and quality. Pressure die casting is one of the fastest-cycling […]
Gravity Die Casting: Accuracy, Strength and Volume
Gravity die casting sits between sand casting and pressure die casting — offering better accuracy than sand, at a lower tooling cost than pressure die. This guide covers how gravity die casting works, its benefits and limits, typical applications, and how tooling and production are managed. For automotive and hydraulic component buyers weighing process options, […]
Sand & Shell Castings: Process, Parts and Materials
As a sand casting manufacturer, Mahati produces castings across cast iron, SG iron, aluminium, steel and brass — from small brackets to large housings. This guide covers how sand and shell casting work, the parts commonly cast, material options, and how quality is checked before dispatch. Choosing the right sand casting manufacturer matters as much […]
Jigs, Fixtures & Tooling for Foundries and Machine Shops
Accurate, repeatable machining depends on more than a good CNC programme — it depends on how the part is held. As a jigs and fixtures manufacturer, Mahati designs and machines the workholding, tooling and dies that keep foundries and machine shops running to tolerance, cycle after cycle. Working with an experienced jigs and fixtures manufacturer […]
Best Pattern Materials & Allowances: An Engineer’s Reference
A pattern is never made to the exact final size of the part. Pattern allowances are deliberate size adjustments built in during design, and getting them wrong is one of the most common causes of casting rejection. This reference covers why pattern allowances exist, the main types, how to choose pattern materials, and how allowances […]
Shell Moulding Patterns: Design, Materials & Foundry Supply
Shell moulding are the backbone of high-accuracy foundry production. Get the pattern design wrong, andevery casting pulled from it inherits the same flaw — thousands of times over. This guide covers what shellmoulding patterns are, how they’re designed, which materials and tolerances they need, and how Mahati suppliesthem foundry-ready from its Bangalore workshop.For any foundry […]
