Choosing the right plastic for a product is a decisive factor for its success. However, given the large number of plastics available, the decision can quickly become a challenge. In this blog post, we give you a detailed insight into the art of choosing plastic and show you what really matters when making a decision.
Define the specific requirements of the product
The first step on the way to choosing the perfect material is to precisely define the specific requirements that the product must fulfill. This concerns:
- Mechanical properties
- Thermal properties
- Physical properties
- Chemical resistance
- Aesthetic features
For example, a housing for an electronic device must not only be robust and durable, but also thermally stable in order to protect the sensitive electronics inside.
The necessary structure of the plastic is derived from the requirements determined. This means that a targeted selection of plastics or plastic combinations is made that can perfectly fulfill these requirements.
MEDIAN’s tip: A thorough requirements analysis is the key to choosing the right material. Make sure that all relevant properties are included in the decision. If you are unsure, it can be helpful to seek advice from experts.
Ensure compatibility with processing methods
The selection of the right plastic also depends heavily on which processing methods are intended for the product.
Different processing methods such as injection molding, extrusion or blow molding have their own requirements and limitations that must be taken into account when selecting materials. A plastic that is ideal for injection molding may be unsuitable for blow molding, for example.
Understanding processing requirements
It is important to evaluate the properties of the plastic in relation to the processing methods. Factors such as melting point, viscosity and processing stability can be decisive in determining whether the material meets the production requirements.
MEDIAN’s tip: To ensure that the selected plastic can withstand the processing methods, it is advisable to obtain expert knowledge. This helps to avoid errors in the subsequent production process.
Take environmental factors into account
Nowadays, sustainability and environmental friendliness are playing an increasingly important role in the choice of materials. Many companies opt for plastics that are recyclable or leave a small ecological footprint.
Focus on recyclable plastics and bioplastics
Many manufacturers are increasingly relying on recycled plastics or bioplastics based on renewable raw materials. These materials offer a sustainable alternative to conventional plastics and can help to reduce CO2 emissions and resource consumption.
MEDIAN’s tip: Use sustainable materials to improve your environmental footprint. Customers are also attaching increasing importance to environmentally friendly products, which can give your company a competitive edge.
Consider the cost-effectiveness and availability of the plastic
In addition to the technical and ecological aspects, cost-effectiveness is also a key factor when selecting the right plastic. The material should be commercially available and affordable in the planned production quantity.
It is often necessary to find a compromise between optimum material properties and production costs.
Cost-benefit analysis
A comprehensive cost-benefit analysis is essential in order to make the most economical choice. This should include not only the material costs themselves, but also factors such as availability and compatibility with the production processes.
MEDIAN’s tip: Make sure that the choice of material is not only technically but also economically sensible. Compare different plastic options and check how they affect production costs in the long term.
Conclusion: The perfect choice of plastic for your project
Choosing the right plastic is a multi-stage process that requires a careful analysis of the requirements and a consideration of technical, economic and ecological factors.
