Thinky mixing silicones for facial and other prosthetics

The manufacture of a medical prosthetic device for a patient’s face or similar area is a highly skilled job; each one is unique, and needs to be handled with great sensitivity, as both functional and cosmetic considerations are involved. It may require careful mixing and colour matching of a silicone moulding compound, with no air entrapment, to ensure appearance and consistency of structure. Jim Dimond, Consultant Clinical Maxillofacial Prosthetist at University Hospital Coventry, explained how the Thinky ARE-250 from Intertronics helped move from a lengthy, manual process requiring a skilled technician, to a short, reliable and automatic mixing process.

Originally, mixing at the hospital was carried out by hand using a palette knife in two stages – mixing and then flattening on a flat glass plate to squeeze out the air. This was arduous – especially for larger quantities required for hands, breasts, facial and other components – issues equally applicable to other silicone applications such as theatrical masks, plaster casting, special effects, model engineering, animatronics, life casting and pattern making. The manual procedure was laborious and very time consuming, as it generally required use of fillers for changing consistency, and small quantities of intense colour pigment being mixed with clear silicones to suit the individual patient.

Seeking a more efficient method of mixing the compound and other components, Jim contacted Product Specialist David Peat at Intertronics for a demonstration of the Thinky ARE-250 non-contact planetary mixer. The Thinky process, by means of both rotation and revolution of the material, mixes and degasses at the same time. The constituents are simply measured into a container which goes straight into the machine, saving time whilst reducing material waste and clean-ups.

The Thinky solution was excellent for small quantities and also worked particularly well with their system of pre-preparing large batches of colour coded silicone - which was especially arduous and time consuming. The Thinky ARE-250 was found to easily process even highly viscous material, and once programmed ensured a thoroughly mixed, bubble-free compound to the required consistency for every batch without further intervention.

Jim commented: “I have been doing this work for about 12 years and for the past 12 months have used the Thinky a great deal. It has allowed us to quickly produce homogenous silicone in large quantities that is free of air, transforming a time consuming, physical task into an automated effortless one.”

Tidy workplace and precise dispensing results from preeflow® eco-PEN450 for Fra …
Franklin Electric, a leading international manufacturer of water and fuel pumps, faced a difficult challenge when tasked with optimising dispensing processes at their Czech production site. The objective was to reduce the waste of UV curing material during the application process. Dispensing equipment previously used by Franklin Electric had been very inaccurate, creating unnecessary waste, high material costs and additional cleaning efforts. After completing preliminary tests, the team at Franklin Electric were

WACKER ELASTOSIL® N9111 from Intertronics is a tin-free single part RTV silicone adhesive sealant, with a neutral cure chemistry, producing a non-corrosive seal that does not inhibit other materials such as platinum cure silicones. This, along with its UL94 V-0 rating, makes it a strong candidate for electronics manufacturing, especially for gap filling, component ruggedisation, and form-in-place gasketing. It is stocked in depth at Intertronics for next-day delivery. Elastosil N9111 is

The automobile manufacturing industry places high demands on suppliers with regard to process reliability, quality and efficiency. To meet these challenges, a preeflow customer had to optimise his application of a two-part sealant to make a form-in-place (FIP) gasket. In his previous process, the dispensed sealant bead exceeded the tolerance limits at the point where the gasket loop completed and the sealant overlapped itself. In addition, a key process variable

Automated application of adhesives, potting compounds or encapsulants, sealants, FIP gaskets, temporary masking, lubricants, or other liquids, fluids or pastes provides productivity benefits over manual application, including consistency, speed and accuracy. As selection of a dispensing robot is sometimes a daunting task, Intertronics, a specialist adhesives and dispensing company, has compiled a short piece of guidance on how to specify a dispensing robot. The full guidance can be found on

Intertronics introduce new nanoparticle deagglomeration technology
The tendency for some nanoparticles to agglomerate or cluster into denser masses can lead to homogeneity and performance issues in their subsequent use. Existing methodologies to de-agglomerate them do not always produce uniform results, or can be invasive and wasteful. The Thinky PR-1 Nanoparticle Dispersion Machine is a desktop unit which can disperse carbon nanotubes (CNT), graphene and other 2D nanomaterials, within a closed container. The dispersion is very even and
