Injection molding technology

Producing sophisticated plastic components in large numbers by injection molding is an outstanding core competence of Balda. Modern machines produce highly precise injection-molded parts which are not uncommonly also printed, individually packed or assembled further before leaving the machine, as part of an integrated process. The injection molding techniques used include, for example, sandwich molding, structural foam molding, in-mold decoration (IMD) and in-mold foiling (IMF), as well as injection-compression molding and insert or outsert molding. While the former makes it possible to enclose an insert in a plastic sleeve, the outsert process is used to injection-mold functional plastic elements in a carrier. IMD and IMF make it possible to produce coloured plastic surfaces with high resistance to abrasion, for example.

From the concept to industrial production.


Maximum precision and efficiency.

Scientific Molding

Balda employs a variety of structured and substantiated methods with which to develop and establish the injection molding process. The aim is to achieve shorter cycle times, higher yields, more rapid process qualification and a generally more robust injection molding process. The following methods are used for this purpose: scientific molding, statistically planned tests (DoE's) and others.


Mold technology

A good mold is the essential basis underlying our value chain. For this reason, Balda participates in major processes, such as the conceptual and engineering design of the molds, actual construction of the mold and its commissioning, including mold qualification, and is normally also responsible for their procurement. Many years of expertise in series production helps us in the development of robust, high- precision molds for the injection molding process. Depending on the complexity of the components and the required volume, we either build the molds in-house or purchase these from established mold makers. To this end, we collaborate not only with highly specialized mold makers, but also with competitive suppliers of standard products.

That is what makes us different and
the best partner.


tailormade production concepts for
the assembly and packaging sectors.

Assembly

On the basis of specifications and the required quantities, Balda prepares tailormade production concepts for the assembly and packaging sectors. These guarantee safe and economic production of the products both in clean rooms and in controlled areas. Different production processes, such as welding, bonding, screwing or riveting, are integrated into the automated process as part of the modular system, thus assuring a high level of flexibility. "In-line inspections" are likewise integrated into the process so that these production stages can be verified on the basis of measurements or visual inspections using camera systems.


Decoration gives the surface of a product its own unmistak­able appearance.

Decoration

Decoration gives the surface of a product its own unmistakable appearance: in this way, the product acquires the desired differentiation and value. Depending on the required properties, we integrate the economically most viable finishing technology into the existing manufacturing or assembly process. Pad printing, for example, is used as an indirect printing technique for symbols and scales. Embossing is the most appropriate technique for highly decorated surfaces and articles with a glossy surface: level surfaces are decorated by hot embossing, while IMD technology is used for curved, transparent and scratch-proof areas.
