Номер профиля: ТЗ-30
Аннотация запроса
Крупная литейная компания Великобритании ищет инновационные высокотемпературные разделительные составы / смазки для форм (антиадгезивы) при литье цветных металлов (например, алюминия) под высоким давлением. Требуется сильный показатель производительности (IP: Index of Performance) [или право интеллектуальной собственности IP: Intellectual Property]. Тип сотрудничества может отличаться, но должен включать как лицензирование, так и полную покупку.

Strong IP is demanded. The type of collaboration may vary but could include both licensing and outright purchase".
Описание запроса
A large UK materials company supplies specialty technical products to the foundry industry. They are searching for innovative technology to allow a step-change in performance of release agents/die lubricants for high pressure die casting of non-ferrous (e.g. aluminium) components.

High pressure casting is a cost-effective process allowing production of precise, high-volume non-ferrous castings of all sizes (e.g. from toys to engine blocks) in a wide range of industries such as automotive, domestic goods, etc. High pressure foundries currently use release agents to coat the steel dies (moulds) with a thin barrier layer prior to casting; this performs a variety of functions such as:
• To prevent soldering or chemical interaction between casting and die surfaces
• To aid the release of the casting from the die
• Thermal control of the tooling
• To lubricate moving parts of the die

Typical current foundry practice:
• Release agents are based on wax emulsions blended with siloxanes or other ingredients. These are usually supplied in concentrated liquid form and diluted with water on-site
• The diluted product is usually sprayed onto the die using automated spraying machines having a multiplicity of nozzles to ensure complete coverage. The more intricate the casting, usually the more nozzles required
• A typical spray cycle can consist of three phases. Firstly water to cool the die to ~250°C to allow the release agent to stick to the surface and not simply vaporise. Secondly the application of the diluted release agent itself and finally a blast of compressed air to remove any residual water.

Current problems encountered in the use of release agents include:
• Blocking of Nozzles - Release agents based on wax emulsions have a tendency to deposit in the spray nozzles and block them, or deposit on the die causing surface imperfections to the casting, resulting in downtime whilst the die and nozzles are cleaned
• Time Consuming - The typical spray cycle of cooling the die with water, applying the product and removing excess moisture between each casting is both complicated and time consuming, limiting the number of castings produced per shift
• Premature Die Failure - The repeated heating and cooling cycles thermally stress the die leading to cracking and eventually the need to replace costly dies.
Технические спецификации/Особые технические требования запроса
The company is interested in acquiring technologies or chemistries (e.g. from outside the foundry industry) that overcomes these three specific problems. Some of these may already be used in other industries e.g. plastic/rubber injection moulding.

The aim is to improve the performance and capabilities of existing products and or to generate a range of new products. Key requirements include:
• Application at higher temperatures (>250°C) (to allow faster casting cycles; protect die from premature failure and reduce blocking of spray nozzles)
• Semi-permanent (coatings which remove the need for spraying between every casting)
• Ability to adhere quickly to steel die, withstand heat of one or more molten metals (750…1400 degrees C), avoid adhesion to the casting surface (maintaining an even surface finish) and avoid compromising the quality of the casting.

Improved eco-friendliness versus existing products is also desirable. In addition all potential solutions should have strong IP content (patents or secret know-how).
