Dispenser cap
Introduction
Momexx Mould Making Experts is a well experienced mould maker in developing and producing injection moulds for the market segment of caps and closures. There are more than a hundred moulds made for a diversity of appliances, from spouts to a cap for drinking packages. Caps and closures are mostly used in the consumer market.
Problem statement
A certain customer produces dispensers. The cap of the product has specific characteristics and design. The special coloring of the cap can only be reached by designing the cap in two parts. The two products are connected by a so-called snap-connection. This connection is steal-save and in such a manner constructed that should construct the perfect fit between the products.
Moulds and craftmanship
The moulds are constructed for the simultaneous production of large numbers of caps and closures. The plurality of the moulds, like the 48V mould, are determined by the demanded, yearly production numbers, cycle time, charged cost-price of the product, risks, investment and maintenance. Furthermore, the extensive amount of experience in this area of plurality makes Momexx besides an excellent plastic mould maker also a good advisor .
Momexx’ wide experience with many different techniques is very useful in the construction of moulds for the caps and closures market. Some examples are techniques used for plurality, different types of hinges, temper evident, automatic closing of caps, 2 and 3 component technology, molded filters and to get screws out of the product.
End product
The upper part of the cap was not allowed to have a visual molding-spot on the outside. Therefore Momexx as an experienced mould maker choses to mold the product from the inside out with a hotrunner. Because of this construction, it is necessary to emit the product from the front mould. This is realized by using two hydraulic cylinders on the front mould.
The lower part of the cap has an undercut and therefore it is essential that the lower part will be deformed without any damages and deformations. This is realized by using moving cores. These movements are coordinated in an exact manner by an in-house developed system.
