Custom Injection Moulding Machines
Pratishna Engineers designs and manufactures custom injection moulding machines for components, materials and processes that a standard machine does not handle well. These machines start from a proven injection and clamping platform and are adapted in the clamp, injection unit, mould handling, controls or automation to suit one application, so the process is built around the part rather than the part around the machine.
Pratishna Engineers is one of the top and trusted custom injection moulding machine manufacturers in India. The Mumbai-based company has 35+ years of experience and has supplied 9,000+ machines to 1,000+ customers, and has built custom machines and equipment for plastics, defence, nuclear, oil and gas and infrastructure customers, backed by in-house engineering and after-sales support.
A custom machine is worth considering when a standard horizontal or vertical machine forces compromises: an unusual mould layout or opening, a part that needs inserts, a second material or an in-mould operation, a material that needs a different barrel or feed, or a production cell that must combine moulding with handling, checking or assembly. The machine is specified only after the part, mould and process are understood.
Custom machines are available in 75, 100 and 120 ton options. Share your component drawing or sample, material, mould details, production quantity and the process problem you want to solve, and Pratishna Engineers will evaluate whether a custom configuration or a standard machine is the better answer.

Custom Injection Moulding Machines by Tonnage
Pratishna custom injection moulding machines are built on 75, 100 and 120 ton platforms. The tonnage is chosen from the part and mould in the usual way, and the custom features are then added to the clamp, injection unit, mould handling, controls or automation.
Because every custom machine is engineered for one application, the final specification is agreed with the customer after reviewing the component, mould, material, cycle and output targets.

FAQs / Buyer Questions
The answers our engineers give most often, before a specification is agreed.
What Is a Custom Injection Moulding Machine?
It is an injection moulding machine adapted for a specific component, material or process. The base clamp and injection unit are proven designs, while the mould handling, controls, feed system or automation are engineered for the application.Is a Custom Injection Moulding Machine the Same as a Special Purpose Machine?
Yes. Both terms describe a machine configured for one application instead of a general-purpose standard model. Pratishna uses the term custom injection moulding machine.How Do I Know If I Need a Custom Machine?
Consider one if your current machine limits part quality, needs manual steps that slow the cycle, cannot fit the mould layout or cannot process the material well. Share the part and the problem, and Pratishna Engineers will advise whether a standard or custom machine suits it.Which Tonnage Options Are Available?
Custom machines are available on 75, 100 and 120 ton platforms. Larger parts are usually better served by the standard horizontal or two-platen ranges.Can a Custom Machine Handle Insert Moulding?
Yes. Machines can be configured for parts moulded around metal inserts, terminals or threaded bushes, with the mould layout, insert loading and sensing planned for safe, repeatable loading. Vertical machines are also offered for insert moulding.Can It Mould Two Materials or Thermoset Compounds?
Two-material parts and thermoset compounds such as BMC and DMC need a different injection or feed arrangement from standard thermoplastic moulding. These applications are evaluated individually for a custom configuration.
Can Automation Be Built Into the Machine?
Yes. Part removal, insert loading, sorting, checking or simple assembly can be integrated into the moulding cell where the application justifies it.What Information Should I Send for an Evaluation?
Send the part drawing or sample, material, part weight, mould dimensions, number of cavities, inserts or secondary operations, production quantity and cycle target, and a description of the problem you want to solve.How Long Does a Custom Machine Take to Build?
Lead time depends on how much of the machine is engineered for the application. It is confirmed with the quotation after the specification is agreed.What Is the Price of a Custom Injection Moulding Machine?
There is no fixed price, because each machine is configured for one application. Cost depends on the base tonnage, the custom features, automation and controls. Pratishna Engineers quotes after evaluating the application.Can Pratishna Use My Existing Mould?
Often yes. Share the mould drawing, dimensions, height, ejection and any core-pull or insert requirements, and Pratishna Engineers will check whether the machine can be built around it.Does Pratishna Provide Installation and Operator Training?
Yes. Pratishna Engineers provides installation, commissioning, operator training and after-sales technical support. The exact scope of support is confirmed with the quotation and machine supply terms.
