Matrix develops the first mold trimateria for the packaging sector

Drafting PU15/03/2006

The company Matrix, whose plant is located in Ripoll (Girona), has just successfully develop the first mold tri-field to produce a cover of packaging. The client which will produce the component, a major multinational, chose Matrix to develop this new technology for the offered technical ability and the favourable conditions that existed to develop it, test her and bring it, because Matrix had a fuel transfer of 155 tonnes with 3 units of injectionrecently purchased.

The new design has required a close collaboration with the customer and the manufacturer of the machine, the kinematics of the mould is of such complexity, which has been necessary to modify the "soft" of the same in order to fulfil the requirements of the mold.

In order to achieve the more ambitious goal of the client, which was the inject the full product with a single machine, had to be installed on this machine a fourth unit of injection and to test the injection of a fourth piece inside the mould trimateria.

The Department of engineering of Matrix has worked several months in order to develop all the technology of the mould, in which applied ideas that are in the process of being patented.

The initial target set by the client, has managed to improve by 10 percent, thanks to an innovative system of rotation. This system allows to absorb the inertia caused by rotating at high speed from parts of the mold and stop it at the last minute, without using mechanical elements or position microphones. The mold has four hot cameras with lateral injection and injection with valve, nozzles designed and built entirely in the Matrix.

The main concept is based on the injection of two pieces separately and their Union by third injection by way of welding, in such a way, that in each cycle is expelled the piece more complete the fourth component.

These new applications open up a new field of enormous possibilities within the packaging sector, allowing develop pieces that can be United or mounted inside the mould.

The Matrix management believes that the future will happen by having production units where the mold will play a very important role, because it should inject several pieces and unite them with injection or mount them inside the mould. This technology need machines of injection with multiple spindles and great flexibility. Traditional methods require a mold and a machine for each element, in addition to the machine Assembly to assemble them. This has been always a great investment in machines and space, so the cost of the finished product is very high.

Great pressure to lower prices which currently suffers the manufacture of moulds and plastic sector requires to find alternative technologies to compete with the new emerging markets, where costs are lower than in developed countries.

With this new development Matrix takes a new step to consolidate its position as leading moldista in the sector and that got his start by opening the new plant of Ripoll in the year 2003.

The total area of 4,300 square meters gives space to install the machine injection acquired by the client together with all the peripheral systems, such as robots, units of refrigeration, etc. and be able to tune the entire system.

The strategy of Matrix has always been the give its customers a complete service, working from the outset in the design of the product, up to the stage of approval of the same in their own facilities. With this objective, empowered the technology centre with a machine Husky of 400 tons, to which a vertical unit of injection Windsor was installed to carry out the development of moulds of shell and a new machine Ferromatik 155 tons with 3 spindles for r & d projects.

In February 2004, plastics universal (number 91) published an extensive article on the Matrix company.
