We offer services of designing and producing the refills of mould injections (insert areas, cores) with optimised cooling system. Thanks to 3D steel printing as well as using traditional methods of processed cuttings, we receive possibilities which allow us to design forming elements with cooling channels. The channels are perfectly fitted to the shape of a produced element which results in guaranteeing the most efficient productive cycle of a tool.

The company’s offer includes 30 years of experience in producing packaging from artificial materials. Currently, for our customers, we are developing other productive services connected with even better and more effective form-producing technology usage. Because of implementing 3D metal printing machines – SLM technology – we are yet able to offer faster preparation and optimisation of moulds so they could be ready for mass production. We obtain shorter productive cycle time which influences on time and budget reduction that are necessary for implementing our customers’ projects.
The beginnings of the company date back to 1981 when the company connected with producing artificial materials was established. Within next several years, the hard work of the owners resulted in a remarkable development of the company. The machinery had been expanded as well as the employment was successively increasing. For the past 30 years we have been dealing with artificial materials processing which we do for our customers. Currently, when we live in times of fast changes and shorter stability of products, we satisfy the demands of the market and offer, not only producing ready goods, but also we optimise productive actions for our customers, yet at the designing stage. Through this action, it is possible to implement new ideas even faster and, at the same time, decrease the cost of production.
At the moment, when the process of mould injection formation is a complex combination of different features, such as: time, pressure, temperature and others typical for the materials and tools, it is essential to minimise and eliminate the problems connected with the final form of the product.
So far, the constructors had to be very experienced while making high quality elements from artificial materials, so all of the features mentioned above, would harmonise. Now, using professional software, we are able to analyse the whole process, avoiding unnecessary cost connected with changes in the process of creating tools. These changes could result in slower implementation of the product.
Renishaw’s source materials
Additive manufacturing of the steel elements allows us to form cooling channels in the forming elements of whatever section and progress. In this way, we can accomplish unlimited designing possibilities of the cooling systems. This leads to reducing the time of cooling and the time of productive cycle, in some cases, even by 60%.
Conformal cooling is an innovative solution in creating injection mould cooling channels. This solution enables to speed up the productive cycle through heating or cooling the mould faster. The channels, designed in this process, are optimised according to constant heating and cooling the whole mould in the shortest time possible. As a result of speeding up the productive process, the efficiency of injection mould is higher and, therefore, the quantity of produced elements is bigger. It leads to decrease of productive cost, assuming the cycle time reduction by 30-60%. This way, in some cases, we are able to produce twice this many elements in the same amount of time.
Thanks to using professional software we can analyse the whole process of injecting and we can optimise the tool without having to produce it and without performing any physical movements. The cooling channel systems and the structural materials are being optimised and analysed in the way of heat conduction, nozzles placement, tools kinematics, etc. The optimisation of the mentioned aspects lets us increase the quality of moulding remarkably as well as decrease the cost of production.
The cooling time of the mould determines a relative part of the whole cycle time. The key structural problem is to adjust cooling parameters in a certain way, so that we could transfer the heat (or heat it) and, at the same time, not cause the mould to shrink inside because of the injection elements were cooled unevenly. Thanks to these technological possibilities, the SLM geometry of cooling systems is not limited by the conventional methods of machining and can be adjusted to the part in a way that eliminates mould temperature differences during the cooling process. This balance enables to minimise the shrinkage of the mould inside and, therefore, reduces the deformation of the final product.
