MMTS offers a wide range of engineering services to the plastic conversion and recycling industry. These services include the manufacture, repair and refurbishment of barrels, screws, granulators, shredders, nibblers, complete extruders, sheet dies, film dies, screen changers, die face pelletisers, gearboxes and a host of equipment either upstream or downstream of the extruder. We also offer the design of barrels and screws using the latest technologies from our experienced designers from Europe and Asia.


We service, repair, recondition, custom-make and import all types of barrels.

In the process of extrusion, injection moulding, blow moulding etc, screws are used to process the raw material into a usable form to make the final product required. However, the performance of the screw is dependant on the condition of the barrel, and we manufacture, repair and recondition most types of barrels, single and twin. All work is done in-house except heat treatment which we subcontract to our specialist engineering partners. We have the capacity to handle barrels up to 6m in length from all(1) manufacturers.

We will come to your premises and do a full assessment of the condition of your barrel and provide you with a report detailing the wear along the entire length. We will also evaluate the profile, straightness, concentricity, surface finish and hardness of the screw as advise of any potential problems. We do not normally charge our local and loyal customers for this service, and consider it a necessary part of maintaining the relationship with the client.


We only do real welding not hard-plating on our screws.

Screws are the heart of any extruder or injection moulder. We manufacture, repair and recondition all types of screws for processing a wide variety of material from virgin PE to dry sawdust. We are able to manufacture and repair , seating washers and tips for injection moulders. We have the capacity to handle screws up to 6m in length from all(2) manufacturers.

We come to your premises and do a full assessment of the condition of your screw and provide you with a report detailing the wear along the entire length. We do not normally charge our local customers for this service, and consider it a necessary part of condition monitoring for plant.

Tie Bars

We can repair and refurbish almost any kind of tie-bar.

Tie bar tolerances are critical to the efficient operation of injection moulders, and we are able to refurbish tie-bars by grinding, chroming and re-finishing almost any tie-bar back to original specification. We can also join tie-bars and repair damaged threads.

On-site Cleaning, Maintenance and Inspection Services

Struggling with skills for stripping and maintaining your extruders? We offer an on-site preventative maintenance and condition monitoring service where we strip and clean your barrel and screw, measure it for signs of wear and abnormal operation and reassemble it. This reduces the risk of damage to the extruder when unskilled workers maintain the machine. We provide a report detailing the condition for your maintenance records.

Granulators (Grinders)

Refurbishment and maintenance of all types of granulators.

We refurbish, repair and rent granulators of all types and sizes. We manufacture the Durl HC26/15 and the Durl GP 12/9 models which are available in models from 15Kw to 55Kw. Please refer to our for specifications. We repair all2 shredders, grinders and granulators.

Shredders (Crushers)

Maintenance and reconditioning of all types of shredders.

We supply and repair shredders of all types and sizes from manufacturers like Untha, Hi-Tech and Satrind. We recondition shredder blades at a fraction of the cost of new ones.

Nibblers (Single Shaft Shredders)

Custom-made and reconditioned nibblers/single rotor shredders.

We make and repair nibblers (single shaft shredders) to reduce lumps to small pieces or shavings depending on requirements.


From big to small, we handle them all!

We build extruders from those with a 15mm diameter screw for use in the medical field up to 180mm diameter for use in the field of recycling, film blowing, pipe and profile extrusion, sheet extrusion etc. We have made extruders for materials as diverse as cement, sawdust, charcoal and cellulose. We also recondition and re-build extruders as well as their barrels, screws, upstream and downstream equipment.

Film Blowing and Sheet Die Refurbishment

Dies and all die-related equipment.

We make and recondition dies for film blowing, flat sheet, profiles etc. For all the dies we refurbish, we remove all defects and imperections on the die-lip and cavity and thereafter we high polish and chrome plate the die to improve product quality and increase lifespan. For sheet dies we can install our customised die lip adjusting feature that allows much greater control over the lip gap and hence control over the film thickness across the length of the die.

Screen Changers, Breaker Plates, Spaghetti Heads, Die Face Pelletisers

Custom-made and standard, repaired and reconditioned.

We manufacture, repair and recondition screen changers, both manual and hydraulic. We have experience with all types including, sliding plate, pivoting plate and cylindrical changers. We manufacure breaker plates according to any specification. We can manufacture spaghetti heads with any number and size of strands for water-bath pelletising lines. We also supply wet and dry die face pelletisers.

Honing Services

Honing some of the longest bores

At MMTS, we have one of the longest honing machines in our area of expertise and we are able to hone bores up to 6 metres in length in-house. We offer general honing services to the public provided that our honing machine has a break in the normal production schedule for our barrel refurbishment service.

Nitriding Services

Offering gas, plasma and liquid nitriding

We utilise several heat treatment and nitriding companies, and due to the volumes we process, we can negotiate better commercial terms. We can include your parts for nitriding in our batches and offer you better value.


Not just for extruders, all types of industrial gearboxes.

We service, repair and recondition extruder, injection moulder, shredder and granulator gearboxes as part of our regular business, but we are able to assist with any type of industrial gearbox.
