Barrels

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.

Screws

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 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

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 and repair 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 Stock Catalogue 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.

Extruders

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.

Gearboxes

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.

Break-down Support

We help you get back into production when things go wrong.

Our works is available on request on a 24 hour basis to support your business if you have a production break-down that requires immediate engineering attention. Please contact our office during offfice hours or any of the technical support team after hours at the numbers on our Contact Us page.

10 inch Rubber Extruder

MMTS was recently contacted by a large rubber manufacturer running a hot feed rubber extruder made by Bridge in the 1960's.

The client had measured the wear on the barrel and screw and believed that refurbishment was required.

Once the barrel and screw had been transported to MMTS, we were able to confirm that the barrel and screw were severly worn and that either replacement or refurbishment was necessary.

Due to production constraints, the client needed the extruder running again when the factory opened in January 2010. This meant that refurbishment was the only option for getting the extruder back into good running condition again.

MMTS set about stripping the extruder drive shaft, and it was found that the Rollway AT-758 thrust bearing was heavily damaged and had to be replaced before the extruder could run again.

The thrust bearing was of a very old design and none were available in South Africa, Europe or Asia ex stock. After a lengthy search, MMTS were able to find a bearing in stock in Minneapolis in the USA on 30 December. The bearing was flown to South Africa via London, which was snowed in at the time, and this caused severe delays, but it finally arrived in South Africa on 11 January 2010.

While the bearing was on its way, the MMTS were hard at work boring the barrel and rebuilding the screw, which went fairly routinely. Once the bearing arrived on the afternoon of 11 Janaury, MMTS only needed 3 hours to reassemble the drive shaft, bearings and screw and deliver to the client, who had a team ready to install.

The client installed the barrel and screw without a hitch and started the extruder on 12 January with minimal impact on production volumes.

Proplas is Huge This Year!

MMTS have had a very active show this year and we have re-kindled our friendships with clients from abroad and our coastal cities.

We have noticed that there is a much more positive outlook amoungst the recyclers and converters, and so we look forward to a much improved volume towards the end this year and next year. It seems that recyclers and convertors have held off until shutdown this year to do maintenance and repairs so we are planning to be open and running shifts to cope with the demand.

It's the small things that Count for Customers

Recently, one of our customers in Malawi was having trouble cooling the pipe in his vacuum chamber on his pipe extruder. The problem was traced to the set of damaged water spray nozzles.

Replacement parts were not readily available in the country and MMTS sourced new nozzles from our suppliers and shipped them to the client in record time.

The client was ecstatic and responded, "Thank you very much for getting these [nozzles] for us. Pipe cooling has now improved and production speed too!".

Change of Banking Account

MMTS was acquired by new owners in October 2008. At the time, we circulated the new registration, banking account and VAT information to all affected parties. However, there are still some customers making payments into the &34;old&34; Nedbank banking account.

We urge all customers to ensure that they have loaded the new First National banking account and VAT numbers into their online payment systems.

Any queries can be directed to our admin ladies at the fax or mail address on our Contact Us page.
