Project Description

When heat welding any plastic its common to end up with excess plastic spilling out from the melt area, this in some cases can be unsightly and needs to be trimmed off.

We can offer different solutions to trimming / milling off plastic excess, from a simple rotation work station where an operator manually trims off the excess using hand tools, to a fully automated 3 axis controlled unit.

We are able to design custom machinery for spru trimming including using multi axis robots where applicable for true 3d applicaitons. eg injection moulded part clean up before being used in a secondary operation

Project Description

Mechtek Plate Handling:

The process of destacking a stacking plates is a challange that is often over simplified

We at mechtek dont take the task lightly and see this as the first of a set of very important stages in the production of a lead acid battery. 

If this process is right, everything else is easier, so a lot of time and effort goes into the hardware design and the software control of this part of the machine, because not only do we want to make a good machine but we want to make one thats robust and productive. 

Our philosophy is good engineering will yeald good results.  Where the plate feeders can be the same, we make them the same.  It makes good sense.  We use the same size motor on a elevator thats lifting 15 Kg as one thats lifting 250Kgs.  Its over spec you could say but it makes the spares required to maintain the machine simpler. 

Our control system for the plate feeder is far and away a leader in this field, we have auto catch up, where if the plate feeder has no plates due to it not being kept full by an operator the line will not make a bad cell or abort a cell, but it will hold station and when plates are available it will catch up and continue on taking the pressure off the upstream supply and preventing producing out of spec cells and running invalid production

The plate feeders are equipped with servo controled elevators to present the stacks at the perfect height, they have servo driven pickup arms for catchup and other control functions, and also twin contra rotating wire brushes that clean the plate tabs 

Project Description

Description - The SEPCOM is a machine composed by a feed device (feeding hopper or a compensator tank depending on whether the material is conveyed mechanically or pumped), a separator casing including a screw conveyor and a cylindrical screen, a compacted solid material outlet module and one or two separated liquid outlets. The drive unit and basement complete the machine.

Function - SEPCOM is a solids-liquid separating machine including a screw conveyor. Using both principles of separation, by gravity and by mechanical pressing, the machine is designed to separate the liquid phase from the solid phase in a wide range of substances such as sludge, sewage, manure, solids-liquid mixtures, vegetables, processing waste and others, where the percentage of liquid inside the solid may be considerably different. The separated solid and liquid phases can be handled in an easier and cheaper way. In some sectors this can even become a source of income.

Operation - The machine receives the material to be separated and conveys it using the screw conveyor inside the separator casing. The liquid phase is separated through the mesh of the cylindrical screen which encloses the screw conveyor. Along its path toward the exit, the material gradually separates progressively the less linked liquid and then the more strongly linked liquid until a plug of almost dry material has formed before the outlet. The plug is continuously expelled through the outlet diaphragm. The machine will automatically find its balance of squeezing force depending on the material. Consequently, it can be used for a wide range of materials without the need for any manual adjustments.

Performance & Technical Features - Benefits

Project Description

Description - WBH Horizontal Single Shaft Batch Mixers consist of a mixing drum vessel with an inlet, an outlet with discharge valve and a venting spout, a mixing shaft, two drum closing end plates that carry flanged end bearing assemblies complete with integrated adjustable shaft sealing unit, and a drive unit complete with power transmission. Ploughshare or inclined blade-type shovel tools rotate as mixing tools in a special arrangement on the mixer shaft in a horizontal, cylindrical drum. The result is a turbulence in the mix that constantly involves all the product particles in the mixing process. The formation of dead spots or slow-movement zones in the mixing drum is prevented ensuring precise mixing. In some cases, to obtain the desired mixing effect, separately driven high-speed choppers can be installed.

Function - The Horizontal Single Shaft WBH Batch Mixer is based on the principle of mechanical fluidisation of the product. The particular shape, position and rotation speed of the mixing tools, creates a centrifugal vortex motion, which allows the materials to be projected in a three-dimensional way and to merge with each other. This ensures that components with a different particle size and bulk density are perfectly blended and mixed with high precision within the shortest possible time. WBH Batch-type Mixers are used for mixing dry powders, granules or short fibres, for moistening, agglomerating or granulating the same materials, or for mixing liquids or pastes with low viscosity.

Project Description

Description - The MBF Micro-Batch Feeder for continuous volumetric feeding of powdery or granular materials consists of a steel-reinforced SINT engineering polymer body (optional body entirely manufactured in stainless steel), a horizontally mounted rotating agitator tool, a feeder screw beneath the agitator tool, a feeder pipe enclosing the protruding feeder screw, one drive unit each for agitator and feeder screw. Tests on product flow and material stress have been carried out to establish optimum body geometry. Agitator and feeder tool geometry and materials have also been tested before choosing an optimal steel and engineering SINT polymer composite. MBF series Micro-Batch Feeders are supplied in food-grade versions with FDA-approval on request.

Function - MBF series Micro-Batch Feeders for powder and granular product feeding are particularly suitable for poorly flowing materials which tend to clog, along with adhesive products. Fed through a bag opening hopper, a bulk bag discharger, or another feeding device, the agitator tool manages to keep the material flowing reducing at the same time the possibility of formation of lumps or bridges. The size of the product particles is of utmost importance when choosing the type of feeder screw. For example, fine, heavy materials call for tapered screws with reduced pitch flights, while granular, lighter materials require standard pitch cylindrical screws. Poorly flowing products with cohesion or bridging problems are homogeneously fed into the feeding zone by the blending shaft which is shaped according to the product properties. Depending on the users individual requirements, MBF Micro-Batch Feeders can be supplied with alternative feeder screws and blending tools and with various accessories. MBF Micro-Batch Feeders have been successfully operating in the following industries:food, building, plastics, chemicals, packaging, environmental technology.

Project Description

Description - The SSC Shaftless Screw or Spiral Conveyor is an alternative concept to the traditional shafted screw conveyor. Material is conveyed by an extra-heavy-duty shaftless screw that slides on a low friction, wear resistant liner inside the conveyor trough housing. The U-section troughs, which are longitudinally divided, are manufactured in carbon steel or in 304 L /316 L stainless steel, including an appropriate surface treatment. Fabricated parts except the screw, which is ultra-heavy-duty, are of the medium-heavy-duty type. The cross section of the lower part of the trough is slightly wider than the side channels to allow for the liner to be inserted in the lower trough part. After complete assembly of the trough the liner is kept in place by the upper trough side channels. At one trough end there is a vertical or flush-type outlet. At the drive end the screw conveyor is equipped with an end plate holding the end bearing assembly with flanged shaft coupling with the screw. The drive unit installed suits the application. The SSC can be loaded from above into the open trough (standard), or through an inlet spout included in a bolted trough cover (option), or from the side through a special side inlet in the loading zone of the trough (option).

Function - The Shaftless Screw (spiral) offers a larger volume capacity and the possibility of handling particularly difficult materials such as those that tend to become tangled up or those that present highly variable particle size. Construction material properties, oversize thickness, as well as a special manufacturing process make the spiral highly resistant and extremely durable. Due to the absence of intermediate bearings, obstacle-free material handling is guaranteed. The completely enclosed trough prevents any material leakage. Trough covers with appropriate gaskets enable odour-free operation and form a barrier to any atmospheric agents to enter the system. At the same time the conveyor offers maximum access to the inside for inspection and cleaning. Maintenance is reduced to the minimum due to a small number of components. There is a vast choice of liners depending on the specific material characteristics. SSC Shaftless Screw (Spiral) Conveyors have been specially designed for handling of difficult heterogeneous materials like urban solid waste, screenings and floating matter, de-watered, thickened, conditioned sludge, packaged food, creams or pastes, waste from:meat, fish, fruit and vegetable processing.

Project Description

Description - The ZX Loading Bellows are used for efficient, dust controlled discharging of dry dusty bulk solids into ships, barges, or stockpiles. These loading spouts are provided with inner tapered cones to contain the flow of material and an outer bellow to provide for dust removal.

Function - ZX Telescopic Loading Bellows are suitable for continuous loading with a maximum flow rate of 850m3/h (500 cfm) of bulk material. At the lower end of the Loading Bellow, a special dust skirt is provided for settling on the ship hold or stockpile. The equipment is available with an electric winch only. A spigot on the header can be connected on site to an external de-dusting filter.

First the Loading Bellow is lowered from the stand-by position towards the ship hold or stockpile. As soon as the bellow outlet has reached the ground, the slack cable switch mounted outside the transmission box stops lowering of the bellow. The limit switch inside the transmission box stops both full extension and contraction of the bellow. Material loading is started by opening the silo outlet valve. Once the bellow is fully contracted, the cable limit switch inside the transmission box stops operation.

Performance & Technical Features - Benefits

• Flexible chute in Neoprene covered by Hypalon makes the bellow weather-proof, highly abrasion and temperature-resistant and durable.

• Two lifting cables outside the material flow raise and lower the loading bellow without cable wear due to material friction and obstruction to material flow.

Options & Accessories

• Single bellow, double bellows or single bellow with internal steel cones
• Bellows manufactured in Neoprene / Hypalon (optionally food grade) or Kevlar
• Control panel with remote control

• Available with capacitance level indicator (optionally twin-type), rotary level indicator or vibrating level indicator
• Outlet vibrator
• Motor-driven winch

Project Description

Description - The BELLOJET ZA Loading Bellows are used for efficient, dust-controlled loading of dry, dusty bulk solids into tankers. The spouts are provided with inner tapered cones to contain the flow of material and an outer double bellow to provide for dust removal. At the lower end of the Loading Bellow, a polymer-coated SINT cone with special sealing properties is provided for connection to the tanker. The BELLOJET dust filtration system, that includes eight cartridges to provide an overall surface area of 10m2 (108 sq ft), is equipped with a 2.2Kw (3.0 HP) fan.

Function - BELLOJET ZA Telescopic Loading Bellows are suitable for continuous loading at a maximum flow rate of 250m3/h (147 cfm) of bulk material. The outlet can be equipped with an anti-spillage device which acts as a dustproof stopper as the Loading Bellow is being raised. The equipment features an electric winch. The fan of the BELLOJET dust filtration system increases the efficiency of the filtering elements. Due to an after-shutdown-cleaning cycle, the filter elements are always in perfect condition at the start of each new loading.

First the Loading Bellow is lowered from the stand-by position towards the inlet spout of the tanker. As soon as the bellow outlet cone has settled on the inlet spout of the tanker, the slack cable switch mounted outside the transmission box stops lowering of the bellow. The limit switch inside the transmission box stops both full extension and contraction of the bellow. Material loading is started by opening the silo outlet valve.

During the filing of the tanker, the polymer SINT coating of the outlet cone acts as a perfect dust seal. At the same time the filter fan continuously sucks dust through the external bellow into the integrated filter cartridges in the upper section of the unit and exhausts excess air. A slack cable switch activates further extension of the bellow as the tanker lowers under increasing material weight. A level monitoring device installed in the centre of the outlet cone signals maximum material level in the tanker compartment and orders immediate closing of the silo outlet valve. Contraction of the bellow back to stand-by position starts after a delay of approximately ten seconds in order to allow the filter to evacuate the remaining dust. Once the bellow is fully contracted, the cable limit switch inside the transmission box stops operation. The preset after shut-down cleaning cycle now provides for additional pulse jet cleaning of the filter cartridges for another ten minutes.

Performance & Technical Features - Benefits

• Built-in dust filter reduces dust emission during filling operation
• Flexible chute in Neoprene covered by Hypalon makes the bellow weather-proof, highly abrasion and temperature-resistant and durable.
• Reverse cone with inside level indicator indicates when tanker is full, raises loading bellow gradually and improves material distribution inside the tanker.

• Two lifting cables outside the material flow raise and lower the loading bellow without any cable wear due to material friction and obstruction to material flow.

Options & Accessories

• Double bellows with optional internal steel cones
• Bellows manufactured in Neoprene / Hypalon (optionally food-grade) or Kevlar
• Control panel with remote control
• Available with capacitance level indicator, rotary level indicator or vibrating level indicator

• Outlet vibrator
• Anti-spillage device
• Metallic parts in contact with the material handled in wear-resistant steel.
