Manumould manufacturing for prototyping and low volume
Manumoulding is the process of choice for prototyping and low volume production. Manumoulding machines are incredibly versatile, and are operated partially by hand, allowing fine attention to detail and close quality control, making it ideal for iterating on designs. PMP’s Manumould operators lean on their extensive experience to guarantee a perfect production, every time.
Manumould manufacturing is ideal for low volume production, such as sampling, prototyping, research and development. PMP can produce as little as a single component in a production run – this has the benefit of rapid iterating and testing of prototypes until a final version is selected

Precise and cost-effective manufacturing
Manumolding is an economical process where cores and inserts can be removed or unwound by hand, thus eliminating the use of complicated and expensive hydraulic unscrewing systems or mechanisms – instead relying on the experienced hands of our expert staff! This has the benefits of lower cost, while also giving our specialist operators more control, ideal for designs that require manual intervention and assessment, such as prototyping.
Although these machines use inserts and loose cores, this does not create a problem for us – at PMP we specialise in this type of insert moulding. Our operators are highly skilled with this process including the use of inserts, core pullers and undergoing multiple operations.

Next level prototyping
Where the manumould process truly shines is for the iterating of prototypes. Our customers never cease to be amazed at how fast PMP can bring concepts into the real world! We also provide 3D printed components in a variety of materials and different levels of finish, to help aid the prototyping and characteristic selection process.
We produce single mouldings for prototypes and R&D, and offer a bespoke pre-production service. This includes a detailed consultation period, in which we will work closely with you to decide on material selection and any improvements that could be made for your product to help in structure or manufacture. At PMP, we always aim to ensure your design is never compromised.
Continuous investment for a better service
PMP has a firm commitment to continuous improvement. We are passionate about plastic moulding and want to remain at the forefront of the industry. That’s why we continually invest in our facilities and out staff, making sure we always have the latest and greatest equipment to enable our skilled team to do their best work.
This means we are quick to incorporate changes into our manufacturing techniques, giving you access to the latest processes and ensuring that we create exceptional products at competitive prices. Let our team of plastic masterminds wow you with their skill and knowledge built up over 45 years!
Manumoulding FAQs
What is manumoulding?
Manumoulding is a manual form of plastic injection moulding typically used for small-scale production or prototype development. Unlike automated injection moulding, where machines handle most of the process, manumoulding involves manual operations such as manually clamping the mould, injecting the molten plastic, and removing the part. This process is often used when full-scale automation is not cost-effective, particularly in low-volume production or when complex mould designs are being tested.
