Case Studies - Kleen Cut 2
This is a filtration unit for removing tramp oil from machine tool soluble oil sumps. Its a mobile unit designed for use in machine shops that can be moved from machine to machine as required.
We have been manufacturing this item for several years in regular batches of 200 off which are then distributed throughout Europe.
The design was made in liaison with the customer by assessing and modernising the original model, the Kleen Cut 1. All drawings were produced by Paramount.
Paramount project managed the whole assembly from manufacturing in house components and purchasing both mechanical and electrical assembled items which were then assembled in house. Paramount then carried out PAT testing, inspection and certification as required.

Case Studies - Resin Cleaner
This is a pedestal free standing resin cleaner with optional centrifuge for cleaning and removal of resin from brushes and roller brushes. We supplied a batch of 30, as seen fully packaged in the background of the main photo sets with proposed forward production of similar sized batches.
Designed in liaison with the end customer, we produced a prototype for approval, integrated design changes and moved onto a preproduction run of 30. Design was carried out using solid works with all drawing and models being produced by Paramount. The system is a solvent tank for cleaning brushes manually by dipping and immersing into the 20 litre capacity tank with an optional centrifuge fitting for pneumatic powered spinning of brushes to remove any residual solvent.
All components were made from stainless steel 304 because of the caustic nature of the process with the bulk of sheet metal being 1.5mm thick.
The work was carried out on the CNC punch followed by CNC folding operations and tig welding where required. As with many projects of this nature there was a lot of assembly of fixtures and fittings such as hinges, pneumatics, lid stays, foot pedals, and labelling etc. The internal mesh tray was fully punched in-house and folded accordingly. The centrifuge housing was sheet rolled and seam welded.
Each tank was leak tested by filling with water and all seam welds were treated with a stain removal process to remove weld discoloration.
The design to preproduction stage took around 6 months as tanks were sent out for approval and testing/sampling in the industry.

Case Studies - Heat Sink Cover
Deep slotted heat sink with multiple faceted faces made to customer supplied 3D model and key point drawing. Manufactured in aluminium 6082T651. We machined 6 components on a DMN650 machining center with a 2 week turnaround.
Job was for an existing blue chip company to which Paramount are a core supplier with a long and well established relationship. The job was competitively quoted for and won based on price and historic performance in quality and delivery. The job was initially being done by a company using a 5 axis machine but Paramount offered a manufacturing solution based on a 3 axis vertical mill with the added assurance of a higher quality of service. This was part of a larger package of work worth in excess of £60k.
Electronic model files were supplied in Step format accessed through a customer FTP portal which is a common project management requirement with many customers. Below can be seen Pro Engineer and EdgeCam screen shots of the programming operation.
The job lent itself to be manufactured on a 5 axis machine, however, due to the capabilities of the Paramounts in-house CAM system we were able to produce the component on a 3 axis machine with an auxiliary fourth axis. This allowed for the machining of the complex curved surfaces using a bullnose cutter to achieve the correct curved surface in a single setup. The outside shape was machined first and then the slots cut.
The component was inspected on the CMM using software to give a direct dimensional comparison to the original customer supplied model. With this particular customer we have a process approval for drawing free manufacture which stipulates that machining tolerances must be within +/-0.1mm all around unless otherwise stated on the drawing.
The component was then alocromed and stove enamelled to a Def-Stan using a local approved contractor, a process that was project managed by Paramount for quality assurance.

Case Studies - Base Plate
High volume production of 3mm mild steel CR4 component manufactured in volumes of 200 off at a regular interval which we have been fulfilling for several years.
The component is about 450mm square with a large central hole that has been produced with a special segment punch on the Amada CNC AE255NT turret punch press.
Component is then vibro finished to remove burrs, degreased and then shipped to the customer.
Customer is a large manufacturing company involved with the fabrication of large scale air flow systems and this component represents a single item of multiple standard parts. Customer is a long term customer that has been using Paramount for components such as this for over 10 years.
