Skin Protector Printer

We have developed a printing machine specifically aimed at the stoma care manufacturing sector. This machine uses the screen print process to print the cut-to-size template, identity code and manufacturers information onto skin protector flanges (wafers).

Through the use of UV curing technology the printed surface is dry in under 2 seconds. This is superior to solvent ink based printing as very little heat is transferred into the skin protector and there are no concerns over ink drying on the screen due to solvent evaporation. Precise control of the UV lamp is through our in-house developed step less control system. Operation is made very simple through the application of a high degree of automation control. Therefore the machine will function with minimal operator supervision.

UV Curing Systems South West

Special Integrated Design is able to offer custom designed mercury arc UV curing systems. We can manufacture units not only for new applications but also to replace or upgrade old and inefficient installations.

Elements of a UV Curing System

  • The control system

We have designed a control system for UV lamps, which provides a stepless output to the lamp. In addition it provides interfacing signals for status and error conditions that can be connected to higher level control equipment, such as a PLC. This system is used on our own screen printer.

  • The light source
Based on the application we can offer flood or focused reflector designs and a selection of lamps with varying wavelengths and power outputs to ensure your product receives the correct dose of UV radiation.
  • The housing
As for the control system we are able to custom design and manufacture UV housings. These feature shielded entry/exit points to eliminate light leakage and if appropriate can be fitted with a shutter system to prevent sensitive substrates from overexposure.

Machinery Refurbishment

Do you suffer from machinery that is continually breaking down due to problems with its control system?

Many older machines are well designed and solidly constructed. Our experience has shown that in many cases the primary cause of problems with these machines lies with the control system rather than the mechanics. This situation is compounded by the equipment not often complying with current safety legislation and with poor or nonexistent spares availability.   In these instances often the best solution is to design a new control system. As well as improved uptime there are additional benefits such as a greatly enhanced operator interface, smaller control cabinet footprint, and in some instances improvements in cycle time can be realised.   Furthermore, in designing a new control system the machine’s functionality can be tailored to your exact requirements.   We have considerable experience in the modernisation and upgrading of pharmaceutical equipment, such as tablet presses and fluid bed dryers.

PLC Training

We offer PLC training - this can be tailored to suit your requirements. We can discuss your requirements and provide at your site a combination of classroom theory and "hands - on " tutorials. Training can be based around your own machines so that the training is relevant to your equipment. We can provide training to persons with no previous knowledge with documentation provided.
