During the injection molding process, costs are reduced by selecting and optimizing plastic materials. Through reasonable material adjustment, production costs can be reduced, product quality improved, and importantly the loss rate can be reduced.

How to reduce the cost of injection molding through plastic material adjustment? The following Universe Plastic Engineers provide the following solutions and ideas.

Choose better materials

1. Replace high-priced materials

If the materials you are currently using are extremely expensive, consider using a more expensive alternative that has similar performance. For example, using chips to replace expensive engineering plastics.

2. Material blending

By blending different types of plastics, costs can be reduced while maintaining desired properties. For example, mixing raw materials with recycled plastics (usually at a ratio of 10%-20%) can reduce material costs.

3. Customized filling

Adding mineral fillers (such as glass fiber, talc, calcium carbonate, etc.) can not only enhance product performance, but also reduce the amount of pure resin and reduce material costs.

4. Use recycled plastic

Secondary materials: Using recycled plastics can reduce raw material costs without affecting product quality and performance. For example, in products with lower appearance requirements, the proportion of recycled materials can be increased.

Internal replacement recycling: Recycle plastic replacements (such as gates and cooling section headers) during the production process to reduce waste and the use of new materials.

Reduce material usage

1. Reduce product wall thickness

If the wall thickness of the product can be appropriately reduced without affecting strength and functionality, material consumption can be reduced. For example, using high-strength materials allows for thinner wall thicknesses, thus reducing material usage.

2. Improve mold design

By optimizing the runner design and gate position of the mold, uneven flow and shrinkage are reduced, further reducing material waste.

Choose materials with better performance

1. Improve injection efficiency

Choose materials with better fluidity to reduce injection time and lower mold temperature requirements. For example, high-flow materials can reduce injection cycle times and reduce energy consumption.

2. Reduce the defective rate

Better fluidity can reduce defects such as bubbles, shrinkage, and flash, and reduce scrap and rework rates.

Choose the right additives

1. Add enhancers

By adding reinforcing agents or stabilizers to improve material properties, such as improving heat resistance, impact strength, etc., you can reduce material waste and improve product durability.

2. Masterbatch

Using high-concentration masterbatches for coloring, rather than general-purpose color powders, can reduce coloring costs and improve color uniformity during the injection process.

Optimize material supply

1. Bulk purchasing

By purchasing materials in bulk, you can get better prices, thus reducing material costs.

2. High-quality supply

Ensure that raw material suppliers are stable and competitively priced to avoid increases in production costs due to material inevitability or constant prices.

Materials testing and standards

1. Material substitution experiment

Through small batch production and experimental testing of different materials, we find the optimal material with both performance and cost advantages.

2. Meet demand standards

Do not choose excessive high-performance materials, but only choose materials that meet product usage requirements to avoid unnecessary cost increases.

Summarize

Through reasonable selection and optimization of plastic materials, injection molding costs can be effectively reduced. While lowering material prices, reducing material usage, and improving production efficiency, it is also necessary to ensure the stability of product quality and functionality to achieve long-term cost savings.
