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.


Barrel Manufacturing, Repairs and RefurbishmentWe 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.


Screw Manufacturing, Repairs and RefurbishmentWe 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 check-rings, 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

Repairs to Tie BarsWe 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

On-site Cleaning and Inspection ServicesStruggling 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.

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.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 imperfections 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.

Because of the limited thickness of the platen, the existing mounting holes were insufficiently strong and MMTS designed new mountings and manufactured complete new brackets.

The client was able to install the platen into the press using the existing tie bars and reduce downtime to a minimum.

On Site Granulator Maintenance

A client that is responsible for destroying counterfeit goods recently needed repairs done to their machine on site.

MMTS were able to go to site, strip the blades from the machine, and send them for sharpening while a full service was done on the machine.

Once the blades were sharpened, MMTS returned and installed the blades and recommissioned the machine. The client has saved considerable costs by not having and full time on site technician and not having to ship the machine to a repairer.
