Plastic Injection Molding Design

Plastic injection molding is a method of producing high-volume precision parts at a low cost.This versatile process can create even highly complex or intricate shapes precisely and efficiently.To ensure success, developing a precise and moldable design is critical.The most effective mold designs are optimized for consistent wall thickness and ease of ejection, among other factors, while keeping manufacturing costs in mind.

Rodon engineers have over 25 years of experience in designing and building molds.This extensive background gives our team the expertise necessary to develop creative solutions for even the most challenging design manufacturing problems. In plastic injection molding, several design factors are particularly crucial for ensuring finished product moldability, quality, and cosmetic appeal.Wall thickness, ribbing, and boss design are all key focus areas for proper part design.

Wall Thickness

Achieving uniform wall thickness is crucial as it will eliminate most of the possible manufacturing defects by ensuring the mold fills and cools correctly.Melted plastics flow into areas of least resistance first.This means that thick-walled areas are the first to fill.

Ensuring a mold design features uniform wall thickness will improve a part's strength, weight, and aesthetics.Parts that are too thick frequently result in unsightly warping, sink, or internal voids.Part uniformity can be maintained by coring or hollowing out thicker regions in the part design.

Ribbing

Ribbing is a crucial component of a part's overall strength, as it supports the walls and other dimensional components.Ribbing typically makes up 50% to 70% of a wall's total thickness, as any greater percentage risks sinking.A part that is intended to be structural should contain ribs as well as supporting gussets if properly designed.These increase strength and help eliminate cosmetic defects, such as voids, sink, and warp.

Bosses

Bosses accommodate assembly through pins or screws.They should be the same thickness as ribs and also require draft to aid in ejection.

Toolmaking

High-quality, precision molds take time and exceptional accuracy to build.They are designed to last for years and can represent a large investment in the manufacturing process, particularly when large-volume manufacturing and complex tooling are involved.Choosing a knowledgeable and reliable toolmaker is essential.

The Rodon Group fabricates the best tooling in the industry, with an exceptional tool warranty to reinforce these claims.We design tools for high-volume, low-tolerance production over the lifetime of your project.As long as we are running a tool that we built, there will never be any maintenance or repair charges.All of our tools are constructed from stainless steel mold bases and cavities, ensuring optimal durability and performance.

Plastic Injection Molding Manufacturing

After a production mold is finalized and the machine has been prepped, manufacturing can begin.We perform an initial run to thoroughly examine components for any part defects.When no defects are found, full production can begin.Rodon carries acomprehensive selectionof injection presses that are classified based on clamping pressure.The machine used depends on many variables, including the type of resin selected, mold size, and the number of cavities.

Depending on the part and the molder's agreement, quality checks take place on a regular basis.These checks inspect for:

• Color correctness
• Strength
• Flash
• Warping
  
  

Plastic Injection Molding Automation

Rodon uses an MRP (Material Requirement Planning) system.This tool allows our manufacturing team to monitor all jobs from the minute they are initiated to the time they are delivered, including all downstream impacts.Our facility of 125 presses runs 24 hours a day, 7 days a week for maximum efficiency.

Plastic Injection Molding Materials

Understanding the differences between plastic injection molding materials is crucial for selecting the most appropriate material for a given application.When selecting the best material for your project, it's important to consider factors such as the end-use environment, desired final appearance, and what industry-specific regulations need to be met.

We expertly help our clients select the most appropriate material for their projects, for high-performing yet cost-effective results.While many types of plastic resins are used in the plastic injection molding process, the top five most common plastic types include:

• Acrylonitrile Butadiene Styrene (ABS)
• Celon® (Acetal)
• Low-density polyethylene (LDPE)
• Polypropylene
• High Impact Polystyrene (HIPS)

Fulfillment and packaging

We pride ourselves on providing Just-in-Time manufacturing to suit the fulfillment demands of each client.Quality control checks are performed as components are sorted, weighed, and sealed for stock or shipment.In keeping with our commitment to automation and conservation, our servo robots provide custom stacking and packing to minimize cartons and freight charges.
