Design & construction

Sundplast started working with injection molding in the 1970s and has since built up a solid knowledge of technology, materials and design. We can offer complete solutions from idea to finished product, including finishing and packaging. Our strength has always been the ability to design and manufacture customized product solutions for our customers. Experienced and knowledgeable engineers can create a product designed specifically for your needs using the latest software and machinery technology.

After going through the design, application and volumes needed, a sales engineer can propose several options in terms of investment tools and unit price. All so that you as a customer can make an informed decision.

We are happy to participate in the early stages of your product development. Let us be your guide to the many possibilities of plastics and save you time. We know what works and what doesn’t, and therefore, with our expertise and technical know-how, we can serve as the perfect sounding board.

Injection molding is the main method for producing plastic parts. The method is used for the processing of thermoplastics but is now also useful for thermoplastics, thermosets and elastomers. All common plastic materials can be processed by injection molding; homogeneous as well as cellular as well as materials with fillers or fiber reinforcement.

Prototyping

For customized products, we can arrange for prototyping during the development phase. This is to enable quick and effective evaluation during the project. We can offer prototypes in many different materials and functionalities to make it as real as possible.

In many areas there is considerable uncertainty as to whether a new design will in practice do what is desired. New designs often face unexpected problems. A prototype is often used as part of the development process, allowing engineers and designers to explore design options, test theories and confirm performance before starting production of a new product. Our engineers use their experience to tailor solutions to your specific requirements. For example, some prototypes may be used to confirm and verify consumer or end-user interest in a proposed design while other prototypes will seek to verify performance or suitability for a specific design strategy.

Generally, a series of prototypes are developed to be tested so that the final design is prepared for production. With few exceptions, several stages of prototyping are used to progressively refine the design. A common approach is to design, test, evaluate and then change the design based on the analysis of the prototype.

Surface treatment, IML & Printing

Since we are a complete supplier in the plastics industry, we have also built up the handling of labeling systems and different types of printing stations as well as handling different types of surface treatments such as vacuum metallization, painting, etc. Plastic products can also be coated with a metallic finish that increases their protection against damage and scratches and gives the surface an exclusive and appealing look. It is possible to get very good imitations of the chrome and aluminum look.

The ability to give plastics metallic properties has many advantages. Plastics are usually non-conductive, non-magnetic, negatively affected by sunlight and have poor abrasion properties. With the right choice of materials and surface treatment, these properties can be modified to create conductive, decorative parts with increased strength, durability, abrasion and corrosion resistance.

Sundplast prints on plastic and has thus developed very high competence in printing on several materials. We use two main techniques. Printing with solvent-based inks that “etch” into the plastic through migration, and heat transfer that imprints from a film to the plastic surface through heat. The result in both cases is a strong and durable printing surface that matches the plastic’s high resistance to abrasion, moisture and chemicals.

We have invested in robotic IML (In Mould Labelling) production, i.e.. a technology in which graphic decoration and labels are integrated directly into the plastic packaging during the manufacturing process. This process takes place in a new system from leading manufacturers and meets all the requirements for the production of packaging.
