By optimizing product design, injection molding costs can be effectively reduced. Product design directly affects many aspects such as material consumption, production efficiency and subsequent processing.

The following are some key product design optimization strategies provided by Universe Plastics engineers to provide you with ideas when reducing injection molding costs.

Reduce product weight

1. Reduce wall thickness

By reducing the wall thickness of the product, the amount of material used is reduced, thereby reducing costs. However, care should be taken to maintain sufficient structural strength to avoid product deformation or breakage. A common approach is to design uniform wall thickness to avoid stress concentration caused by local excessive thickness or thinness.

2. Use ribs and stiffeners

Where structural strength is required, rigidity can be increased by adding stiffeners or ribs without increasing the overall material thickness. This can effectively save materials.

Simplify product structure

1. Reduce complex shapes and features

Complex geometries may require more complex mold designs, increasing mold processing and maintenance costs. By simplifying product design, processing time can be reduced and mold manufacturing expenses reduced.

2. Reduce the number of parts

By integrating multiple parts into one part through design, reducing the number of parts can save assembly time and processes while reducing the number of molds and material consumption.

Optimize product demoulding design

1. Increase the demoulding angle

Make sure there is sufficient demoulding slope in the product design (usually 1 to 3 degrees is recommended), which can reduce the resistance of the product during demoulding, avoid mold damage and improve production efficiency. Design without draft may lead to product deformation and increased mold wear.

2. Avoid excessive undercut designs

Complex undercut or buckle structures require the use of special mold components such as sliders and ejector pins, which increases mold costs and injection molding difficulty. Avoid these designs where possible, or mitigate undercuts through redesign.

Reduce or avoid post-processing steps

1. Reduce subsequent processing requirements

Avoid designing parts that require secondary processing (such as drilling, cutting, welding, etc.). By completing all necessary features in one go in injection molding, additional tooling costs and time are reduced.

2. Design appropriate surface texture

Achieve the desired appearance by directly designing the surface of the injection molded parts, avoiding subsequent surface treatments such as painting and polishing, and saving processes.

3. Use undercuts and buckles skillfully

Reasonable buckle design can not only reduce assembly costs, but also reduce the need to use screws or glue for connection. The buckle can be formed in one pass and provides reliable connectivity and detachability, thereby reducing assembly time and material costs.

4. Eliminate complex fitting parts//www.universemolding.com

By optimizing the design and reducing mating parts (such as threads, fasteners, etc.), the manufacturing process can be simplified. Try to design the matching parts into one piece to reduce the assembly process after injection molding.

Other optimizations

1. Suitable for automated production

When designing your product, consider how to make the injection molding process and subsequent assembly more suitable for automated equipment. Avoid designing complex parts that require manual component insertion, manual assembly or handling, reducing labor costs and increasing productivity.

2. Consider modular design

If the product is a large or complex structure, consider designing it into multiple modular sections. This not only reduces mold design and manufacturing costs, but also allows for flexible response to product design changes or upgrades.

Summarize

Through reasonable product design optimization, material waste, production time and manufacturing complexity during the injection molding process can be effectively reduced, thereby reducing injection molding costs. Adopting strategies such as simplifying structure, reducing weight, and optimizing demoulding design can improve the economics of product manufacturing and maintain production efficiency and quality.
