The mould or die refers to the tooling used to produce plastic parts in injection moulding. A mould can produce several copies of the same parts in a single "shot". A tool with one impression is often called a single cavity mould. A mould with two or more cavities of the same parts is usually called a multiple cavity mould. Some extremely high production volume moulds (like those for bottle caps) can have over 128 cavities.

In some cases, multiple cavity tooling moulds a series of different parts in the same tool. We call these moulds family moulds, as all the parts are related—e.g., plastic model kits. Some moulds allow previously moulded parts to be reinserted to allow a new plastic layer to form around the first part. This is often referred to as overmoulding. This system can allow for production of one-piece tires and wheels. Moulds are typically constructed from hardened steel, pre-hardened steel, aluminum, and/or beryllium-copper alloy.

Variety of widely used products are made from Injection moulds. If we just look around your desk or home we can find a multitude of injection moulded products, from bottle tops, remote control casing, console covers, syringes and many more.

Mahadevi Tools is one of the most well-known manufacturers, specialising in plastic mould making to satisfy the needs of consumers. We've produced plastic injection moulds, injection moulds, and custom moulds for a variety of organizations, using our many years of mould design and product design experience. Our company's mould designs may be used in a variety of sectors. This is how we assist our consumers.

For injection moulded parts, our attention to detail provides you with the necessary assistance.

  • Working with a team of skilled engineers who communicate with your designers to understand the application's needs. Our experts determine how the part is being used, its coordination with the other components within the assembly, the loads it is likely to experience and the method of fabrication.

  • During the tooling phase, we considered how the injection medium enters, fills, and cools within the mould to create the component, as well as ensuring the part is simple to produce and assemble.

  • We focus on ways to minimise stress and prevent early warping or cracking.

  • We have skilled engineers that understand how to avoid sharp corners to reduce strains on the component and to prevent fast transitions from one feature to another.

How do we help you reduce your Mould Costs?

Injection moulding can be an expensive process, but there are several ways in which we can reduce mould costs, including:

  • Using a core cavity approach
  • Remove unnecessary features
  • Reducing cosmetic finishes
  • Eliminating unnecessary undercuts
  • Designing parts that self-mate
  • Considering your part sizes
  • Modifying and re-using existing mould
  • Use a multi cavity or family type of mould.

Skills you can rely on

We are a dependable injection mould maker who designs and manufactures injection moulds according to customer specifications. We have vast expertise in the fabrication of plastic components as a reputable mould maker. We can adapt the system of the customer thanks to our many 3D design software platforms. You may come across a number of injection mould manufacturers, but only a handful have the experience that we have in producing high-quality moulds and plastic.

Consulting and providing suggestions regarding mould.

For the construction of remarkable multi-cavity moulds, several types of moulds must experience a high level of accuracy and perfection. Furthermore, when clients are undecided about which mould to use, we aid them in meeting their goals. In general, our specialists examine the data and determine which sort of mould will best meet client needs. We have the required expertise and experience as a reputable injection mould maker to build, change, and update moulds based on your requirements.


We know how to make moulds for a variety of applications thanks to our many years of experience and competence in injection moulding design. Plastic injection moulds, on the other hand, may produce a variety of components. We walk our customers through the mould development process to ensure that the components are suitable with a wide range of materials and that finishing costs and hassles are minimised.

We only need to know the overall properties of the polymers used for design purposes. We'll go over some of the most important properties of plastics as well as some design concerns.

When it comes to plastic injection moulds, these are some common plastic materials used

  • Crystalline Plastics
  • Amorphous Plastics
  • Polyethylene (PE)
  • Polypropylene (PP)
  • Acrylonitrile Butadiene Styrene (ABS)
  • Polyoxymethylene (POM)
  • Polystyrene (PS)
  • Resin
  • Nylon
  • Polycarbonate
  • Thermoplastic Rubber
  • Fiber Reinforce Plastic
  • Glass Filled Nylon
  • Acrylic

The list, however, does not end here. A wide range of materials are available. As a result, selecting the appropriate plastic material for your custom injection mould is critical. Important material attributes, including as durability, flexibility, performance, texture, density, and colour, must be evaluated based on the part's intended use and functioning.

It's also crucial to consider the shrinkage and mould flow rates of each material. Understanding these requirements will help you avoid problems like warpage, sink marks, and colour streaks, which can compromise the dimensions, tolerances, and surface polish of your product. If the components were first manufactured from a single plastic material, switching to a new material for subsequent production runs may cause the part's dimensions to change, as each material has a distinct shrink rate.

The advantages of plastic injection moulding include excellent precision and repeatability, as well as speed, cheap cost per component, and a wide range of polymers.

With the information above, we hope you are more educated and can apply what you've learned to improve your plastic injection moulding components. If you're developing a plastic item, MAHADEVI TOOLS, an injection mould manufacturer, is a great place to start. MAHADEVI TOOLS can help you bring your product to life swiftly and efficiently by using years of knowledge, a network of suppliers, in-house injection mould design, and mould fabrication.
