Therefore molder always recommends uniform wall thickness for defect-free injection molded parts. Uniform wall thickness in injection molded parts ensures molten plastic is not passing through varying restrictions in the injection mold. The Following factors affect the quality and consistency of injection molded plastic parts. Aside from the main areas of a part, uniform wall thickness is an important design element for edges and corners. Adding generous radii to rounded corners will improve the design of a plastic part by reducing stress concentration and increasing the material's ability to flow.

These engineers oversee all process steps, from designing to end-product creation. Plastics engineers are also highly skilled in handling, programming, and maintaining different types of machinery connected to plastics manufacturing. Sharp corners in plastic parts can lead to high stress, restrict material flow, and reduce part strength. Therefore it is recommended to add a radius in the plastic part design for injection molding. The maximum recommended rib height is less than three times of nominal wall thickness.

In other words, a part can accommodate more variation in the injection molding process. Industrial designers are continually challenged with preserving their concept design intent as it is transformed into a production design. This delicate process can be managed efficiently if the industrial design firm is knowledgeable about mold design and the specific plastic molding process. IDS has a comprehensive understanding of mold design and routinely translates its highly innovative designs into practical, easily molded plastic parts. In plastic part design, recommended rib thickness is 0.5 to 0.75 times the nominal wall thickness to avoid shrinkage in injection molded parts. All designs are verified before being released for production to avoid costly mistakes.
What does DFMA - Design for Manufacturing and Assembly - mean?
But it is not possible to follow all design guidelines because of product design constraints. Criador Labs has vast experience in plastic product design and manufacturing. Depending on the above data observed and the type of manufacturing selected, the CAD modeling is moved forward. Depending on the manufacturing method, many variables change and need to be kept in mind. For eg, for injection molding, it is advised to keep a Uniform Wall thickness within a range of 1.5mm - 3 mm. Its versatility can meet almost any design requirement, and its lightweight, durability, and versatility in color, touch, and shape give it significant marketing advantages.
Also, it allows its incorporation into any production process or final product. For that reason, it is undeniable that the market for plastic products has a prominent place in the set of the economy. In this stage, all the decisions are taken from the economic, technical, and work process point of view (final design, expected manufacturing volume, estimated manufacturing cost, and production speed) to obtain the final product. At this point, it must be considered that there are companies that only design, but do not manufacture and vice versa.

It is generally called ‘tool’ and is designed by a tool designer and fabricated by an internal or external tooling supplier. The tooling concepts must be addressed at an early stage in the design process, as the tooling costs are highly dependent on the design features and the specifications for appearance. A tool consists of two mold halves, which form a cavity that defines the shape of a final part. Your plastic part design should always ensure injection molded plastic part quality. We can achieve a wide injection molding window if the plastic part design is as per design guidelines.
For over 35 years, we’ve consistently delivered high-quality products on time and on budget to optimize our client’s marketing, manufacturing and functional needs. According to the British Plastic Federation, plastics versatility can meet almost any requirement from designers and customers. Also, their lightweight, durability, and versatility in color, touch, and shape give tremendous marketing advantages. It also worth to mention that plastic is an accessible material to work and mold. It has a low production cost, a low density, is waterproof, an excellent electrical insulator, good thermal insulation, and resistance to corrosion and many chemical factors.
This limitation precludes them from providing you with the optimum manufacturing process for your application. All products are ideally matched for injection molding due to part size, production quantities, or materials. An experienced plastic design corporation like IDS will analyze your unique requirements and direct you to the optimum process. This objectivity benefits you with the most cost-effective plastic molding option to amortize your investment. To sum up, product designers shall injection molding plastic part design guidelines during plastic part design to ensure part quality and ease of manufacturing. But wherever you can not follow design guidelines, you can reduce the risks by performing simulation studies.
Sharp Corners in injection molded Plastic Parts
The phrase “Design For Manufacturing (DFM)” describes the affect a product’s design has on its ability to be mass produced. If a product is too thick, has undercuts or insufficient draft, or poorly designed features, it will increase cost, slow production, and create other delays in getting your product to market. Conventional polymers can be replaced with biopolymers, recycled material.
Prototypes that are impacted or fatigued might require machined or molded prototypes. More oversized products that are rotationally molded or thermoformed are better suited for computer simulations. Selecting the optimum prototyping method and identifying critical design parameters are crucial steps in the plastic design and development process.
Industrial designers will always ask for zero drafts, But mold designers need max possible draft angle. Recommended inside corner radius in plastic pat design is more than 0.5 times the nominal wall thickness. Whereas recommended outside radius is inside radius plus nominal wall thickness. In design, it’s not always feasible to provide uniform wall thickness in all sections. Therefore following points are recommended to reduce the impact of non-uniform wall thickness. Plastic part manufacturers always recommend following the maximum possible design guidelines to manufacture defects-free plastic parts.
Designboom has received this project from our DIY submissions feature, where we welcome our readers to submit their own work for publication. Debris is launched during Milan Design Week 2024 budbrand AWARD 2024 U-25 exhibition, showcasing its innovative approach to sustainability and design. To mark Earth Day, which has the theme of "Planet vs Plastics" and is campaigning for "the end" of the material, we investigated whether it's time to bid farewell to the 20th century's wonder material.
Corners can lead to stresses, limit material flow, and often reduce part strength.

News from Dezeen Events Guide, a listings guide covering the leading design-related events taking place around the world. Although initially synonymous with stockings, the term nylon has since expanded to include a whole family of plastics composed of polyamides. These can be found in toothbrush bristles, films for food packaging and moulded components in cars and electronics. Extruded ABS pipes are more resilient than their PVC counterparts, making them suitable for constructing sewer systems and being repurposed into a corrugated seating collection by designer Phan Thao Dang (above).
The material is also used to create plastic bottle caps and even when brands such as Evian claim they've created bottles from "100 per cent recycled plastic", their lid is generally made from virgin HDPE to guarantee durability. The resulting polymer can be blow-moulded to form single-use bottles, stretched into a film for food packaging or spun into fibres to create polyester fabric, which accounts for more than half the world's synthetic fibres. Taken together, plastic production and incineration were responsible for more than 850 million metric tons of greenhouse-gas emissions in 2019. Although certain plastics – such as rubber, which is derived from the rubber plant – occur naturally, most modern plastics are synthetic and more than 99 per cent are derived from fossil fuels. Defined by their plasticity, they have long carbon chains called polymers at their backbone and can be moulded, extruded or cast into any desired shape from films to textile fibres. If a product can be modified to eliminate these features, it can save significant time and money.
