Sophisticated Technology – New Injection Molding Machines
Machine fleet at MENSHEN is expanding further
Packaging has been part of people’s daily lives for many years. After all, no matter whether it is food, cosmetics, cleaning agents, chemicals or other everyday goods, most of the things we need would break, get lost or perish before they reached us – were it not for packaging. The closure as the “top of the pack” plays a very special role in this. Besides its most important property – namely to prevent leakage – it is an eye-catcher on the retail shelf, draws attention to the pack as a whole, and contributes significantly to the success of the product. Because requirements on the closure are so high, it is one of the most highly developed products of our time. This is a challenge that MENSHEN has been meeting for more than 45 years.
Consequently, a closure must not only keep the pack tightly sealed, but also be easy to open and close, feel pleasant in use, and at the same time look good. This means that the manufacturing methods also have to be continuously advanced, optimized and adapted to the needs of the market.
This is where so-called cube molds play an important role. The use of this type of tooling is a remarkably efficient alternative when producing closures made of different components, materials and/or colors. Cube molds are characterized in that they have not only one tooled surface as is the case with conventional molds. Instead, four sides of the cube are utilized for molding, with all the phases needed in the production process taking place at the same time. While the first component or color is injected at the first station, cooling is carried out at the second one, the second part of the closure is produced at the third station, and the finished parts are ejected at station 4. After that, the mold rotates and the process starts again. The cycle is very fast and thus extremely productive.
Special machinery is called for when utilizing these cube molds; machines that meet the specific demands of this manufacturing technology. MENSHEN have now taken delivery of an injection molding machine that fulfills just these conditions. A heavy-duty crane was needed to heave this particular machine – weighing about the equivalent of 35 middle-class automobiles - from the truck prior to being transported to the designated production hall. Two further, identical machines are to follow in the second half of the year. Besides the construction of a new, additional production hall, this will be a further investment in the Finnentrop site.
