6 Benefits of Injection Molding Robots

Injection molding is defined as a process of manufacturing that produces parts on large scale. It is prevalent in mass production processes whereby the same part is reproduced hundreds or thousands of times in succession.

The Injection molding process is whereby molten plastic or metal is injected into ceramic, steel or aluminum molds that are shaped like the final product, and then squeezed at high pressure. Robotic automation has many benefits, and it is in use in many industries. Here are five key benefits of using injection-molding robots.

Increase in Throughput

The increase in throughput when injection-molding robots are used is undeniable. One advantage of robots is the increased production pace. Injection molding robots work faster than humans do, and the speed increases the amount of product being produced per cycle. The robots work continuously and do not stop, whether day or night. All they need is programming, and they continue working until commanded to stop. This goes without saying that profit also increased as more products get into the market.

Shortens the Injection Molding Cycle Time

When the injection molding process is automated, there is the robot arms plus a computer that controls the process. Heating, casting and cooling processes are therefore regulated carefully, and there is no estimation or control by human workers, which improves efficiency and reduces the molding cycle time for every batch produced. A robot arm does not have to wait for the batches to cool and less time wasted in between cycles.

Increases Precision and Reduces Waste

In any injection molding cycle, depending on the precision level, some scrap, or excess material remains. The scrap is recyclable, but this also requires another step where the scrap is removed, slowing down the injection molding process, and interrupting efficiency. When you automate the process, the injection robots have a high precision level, meaning any extra scraps, if any, are very minimal. With the waste reduction, there is a reduction in costs, and removing the scrap does not happen many times.

Better Quality of Products

Robots are not error-prone like human workers. The errors may occur if human workers feed the wrong material amount into the injection-molding machine. A well-programmed robot cannot make such errors, which means each product cycle is similar to the next. When you automate the injection molding process, it turns into a closed system where only the machines are part of the system. Other outside elements such as contaminants that might affect quality are no longer present.

Automation of Secondary Manufacturing Processes Increases Efficiency and Profitability

By choosing to adopt the use of injection molding robots, it means any secondary processes are automated as well. These processes include inspection, pick and place, and packaging. The whole manufacturing process becomes very efficient, leading to more production, increased sales and more profits. When you automate the manufacturing process, you do not need a large human workforce, which contributes to a reduction in labor costs and more profits.

Injection Molding is Repeatable

Automated inspection molding is repeatable, meaning that every product is identical to the other. When you are trying to achieve brand consistency and achieve a substantial production volume. This also increases profitability by a considerable margin, as you can reproduce many replicas of the same product in one cycle.

Conclusion

Automating injection molding has many benefits such as increased throughput, shortened cycle time, increased precision and less waste. Robots work faster than human workers, and with no breaks in between. A robot will not stop unless programmed to do so. This increases production and as profitability as well.

With robotic injection molding, you can automate secondary processes associated such as pick and place or inspection. Since automated injection molding is repeatable, it means you can churn out identical products and maintain brand consistency. This guarantees you higher sales and a higher volume of products.
