Built to do the job and built to last.
Over the years we have helped to provide custom solutions for applications where an off the shelf product is not available.
Predominantly based around items within our product range, we have provided from our own custom designed or modified Comco work cabinets to accept long parts to motorized part holders in a harsh abrasive environment to our newly developed SA150 and SA3000 precision surface abraders and our BV9000 Wafer Beveller. Our latest custom machine is a new version of the SA150 - the SA152 Surface Abrader.
Please contact us if you have a custom or automation requirement. See below for some of our custom/modified products:
For the BV6600 Rectifier Beveller, the customer needed to abrade two sharply cut angles to form a smooth edge bevel. Two Comco Accuflo blasters were added to perform the abrasive blasting (one for the shallow cut and the other for the steeper cut. The two abrasive cuts were set up so the steeper cut is carried out using a fixed nozzle and the shallow cut is made using a motor driven nozzle.
An LED backlight (on the left) allows control of the image displayed on the monitor to see the profile being cut.
The wafer above is shown on the monitor and allows the operator a clear image to see the profile being cut is correct.
We recently supplied a micro Blaster system that needed a controlled blast cycle for three separate Accuflo blasters. Each Blaster needed to de-burr a specific section in a machined part. The three separate areas that needed de-burring each required a different timer setting for each area. By integrating a Comco External Blast Timer (MB2300-1) with each of the Accuflo's and by using a custom made control box, all three blasters could be switched by a single footswitch helping to maintain consistency of the process.
The customer supplied and fabricated the custom jig required to hold the part and the blast nozzles. The white metal stand seen in the picture above was also supplied by us in to order to help organize the system on the customers workbench.
We had an unusual request for blasting the back of flex circuits to improve the laser solderability of the parts. The backing was too reflective and meant that the laser welds were not always consistent. A custom machine was built to create a uniform area over the back of the area soldered that would not reflect the laser and improve the efficiency of the weld.
The simple to use, machine has tooling to process 10 flexes on each cycle. A simple PLC controller takes care of the machine operation to control the pneumatic arm and the interlocks for the door and blast control.
Inside the blast chamber, the slot in the tooling allows a uniform abrasion of the parts and allows easy loading and unloading of the parts.
The machine set up with a Comco Microblaster.
The Epak Electronics Ltd custom BV9000 Rectifier Beveller processing the pulley wheel style bevel in the edge of a wafer (shown in the middle picture below).
The machine uses micro-blasting technology (like a miniature sand blaster) to firstly square off the edges of the wafer and to then create the pulley wheel bevel. In this application, alumina oxide is the blast media used.

The Epak Electronics Ltd SA152 Precision Surface Abrader will abrasively clean or texture thin flat parts up to 170mm wide, 320mm long and up to 20mm thick. When used with resistive masks, patterns, holes and surface structures can be etched into surfaces in glass for use in MEMS, LAB-ON-CHIP and Micro-machining applications. The system includes either a Comco DF1400 Directflo or Comco PF2400 Powerflo abrasive blaster that sits underneath the machine on a wheeled trolley.
The SA150 precision surface abrader, SA150, will abrasively clean or texture thin flat parts up to 150mm wide, 150mm long and up to 20mm thick. The system comprises of a Comco DF1400-2CE abrasive blaster, which sits underneath the main unit on a gurney. Connected into the back of the main table is an extract port for connecting to a suitable dust extractor.
The standard machine occupies a floor area approximately 700mm x 700mm and the conveyor height is 1100mm from the floor. The overall conveyor is 600mm long and is 170mm wide. Abrasion resistant polyurethane belts make up the conveyor belt.
Parts are placed on the conveyor belt on the left hand side of the machine and are run under a laser sensor, which automatically detects the front leading edge of the part. Parameters for part length, pass width, pass speed, the number of passes across the part, the index distance between passes, and the reprocess steps, can all be changed via the SA150 control panel. A save feature allows the current process parameters to be saved into memory.
