As the techniques & equipment

Engineers actually

know about

Plastic moulding solutions
only stretch as far

When stubborn troubleshooting persists and engineers run out of test options

Teams need access to new troubleshooting ideas and exposure to radically different moulding equipment to get into production.

Because moulding solutions only stretch as far as the techniques and equipment engineers have actually worked with.

Built by 3 generations since 1976, Eastern Plastics Machinery® has spent 50+ years helping tier 1 manufactures across the UK, EU and Middle East get access to the world’s most radical technology exclusive to Asia and not in the mainstream western market, as well as pioneering plastic moulding techniques direct from Japan’s R&D equipment experts.

Solving highly complex troubleshooting for global clients and expanding their teams technical knowledge to gain competitive advantage.

1 Mission

Our exclusive partners equipment all share our 1 mission:

An alternative approach to standard equipment build, to resolve the previously un-mouldable across EMEA.

Our main 5 partners include:

SEIKI HOT RUNNERS
With independent Gate Tip Heater® patented technology

JSW MOULDING MACHINES
Injection mouldings largest R&D steel specialists

  • Prone to degradation, engineering plastics can be challenging to mould.

    Our partners at Seiki realised standard hot runners built with 1 body temperature control ended up being the cause of degradation and productivity loss.

    They created a uniquely patented tip heater valve and probe hot runner design with a simple to operate gate temperature control to solve this problem.

  • Engineering plastic is hydroscopic and absorbs moisture from the environment, failure to remove this moisture or the fines and dust prior to injection moulding causes common problems such as silver streaks, black specks and rejects that can ruin your production KPI’s.

    Our partners Matsui recognised standard drying systems were actually the cause of these common problems.

    Matsui cut drying time by half, keep production output constant and eradicate silver streaks and black specks, with their worlds first continuously cycling honeycomb desiccant rotor and hopper filtration system.

  • At ejection and assembly, teams can loose a frustrating amount of hours due to lack of product consistency and have no choice but to waste expensive material due to multi-part variation, or, at ejection - deal with repetitive breakdowns and tool breakages causing teams to slow robot movements (reducing productivity and your bottom-line).

    Born originally from the small and intricate pen production and assembly in 1970, Sailor Robotics recognised the need for robots that give their assembly teams fast and highly consistent products that dramatically reduce faults at assembly.

    They created a wide range of lightweight robots with rack and pinion technology and unique ‘harmonic curves’ in the robots movements, able to deal with sudden changes in movement without vibration, reducing breakdowns to years not months, halving takeout time and keeping part consistency.

Three generations of passion.

Started by technical engineers - the late Ken Siddall in 1976, joined by his son Chris Siddall in 1978, and later joined by Chris’ daughter Michelle Siddall in 2025 - Eastern Plastics has been a leading supplier and technical support service over 50 years, originally based out of the UK and since expanding to the Middle East.

Flying to and from Japan for a decade throughout the 1970’s, Chris Siddall moved from his trade in jewellery and diamond mounting and trained as a expert engineer in Japan alongside mastermind of research and development at Meiki (part of Japanese Steel Works) Hideo Horiguchi San at their R&D laboratory and test centre in Kwagucci, Tokyo.

He developed a deep understanding how revolutionary technology in Asian was built from the ground up, as well as developing patents, researching molecular materials and understanding the scientific reasons behind ‘why’ machinery throughout the injection moulding machine network react they way they do and why Asia’s design was a pioneer in its space.

Bringing this alternative technology and unstoppable productivity to plastics moulding manufacturers became Chris and Ken Siddall’s lifetime passion, and has helped solve some of the most complex injection moulding technical problems for some of the biggest clients across the fields of electrical, automotive, healthcare, medical, component and waterworks including Johnson & Johnson, John Guest and Molex.
