We master many technologies - and
we are constantly developing them.
Different approaches are considered, depending on the customer’s request. Thanks to our experience, we know exactly what matters and the fastest way to reach the goal. Find out a bit more about injection moulding techniques and materials here:
Compact and multi-component injection moulding
Single-component (1K) compact injection moulding is a cost-effective way of producing functional plastic parts (e.g., storage boxes, containers, casing covers, large parts, etc.) with sophisticated finishes, precise dimensions and a wide variety of products.
With multi-component injection moulding, parts are made out of different plastics, e.g. hard-soft combinations and compact moulded parts in different colours, using one machine. The advantage: high-quality surfaces with a unique feel – without any additional assembly.
GIT cavity (gas injection technology)
The GIT cavity technology makes it possible to economically produce thick-walled, hollow plastic parts without any sink marks. During injection or afterwards, a needle is used to inject gas into the moulding, creating a cavity. Parts produced in the GID process are extremely stable, low in residual stress, highly rigid and have less distortion. Good surfaces can be produced, the weight can be reduced and cycle times shortened, even with thick-walled parts.
The difference to conventional injection moulding is that with the gas injection technology a filler, usually nitrogen, is injected into the plastic in one process-specific step resulting in a cavity in the component.
The in-mould process is an injection moulding method during which plastic is injected around the decoration inserted in the injection mould, e.g. fabric, wood veneer or any printed or structured foils. Sophisticated surfaces are created in just one step. Products can be cost-effectively and permanently provided with customised branding using this.
Plastics, biomaterials and PET
SLG uses a variety of plastics, biomaterials and PET in production. The often underestimated plastics (polymers, polycondensates and polyadducts) offer a wealth of design and production options. We use materials from 100% renewable raw materials, high-quality compounds with plastic components and completely bio-degradable materials in biomaterials. Granular PET recyclate is also suitable for production by injection moulding. By the way: all plastics used at SLG are fully recyclable!
FIM is suitable for thick-walled, solid and inherently stable housing parts for high-quality devices. This method effectively avoids sink marks and any possible distortion. The mouldings are therefore extremely accurate.
There is a high degree of design freedom for engineers and designers. One major advantage: since any wall thickness differences can be produced without sink marks, FIM is suitable for rigid, custom-fit designs with high intrinsic stability.
