Injection molding automation: Efficient automation solutions for the plastics industry
Injection molding is a key manufacturing method for producing plastic parts and components. In this process, molten plastic is injected into a mold to create products with high precision and detail. This process is intensive and repetitive, making it particularly suited for automation. By automating various steps in the injection molding process, manufacturers can reduce production costs, increase efficiency, and ensure consistent product quality. At Wemo, we specialize in developing automation solutions for injection molding, with our linear robotic systems playing a vital role.
How automation can improve the injection molding process
In today's manufacturing, efficiency and operational reliability are critical factors for profitability, and automation solutions for injection molding provide a clear competitive advantage. Automating processes such as part extraction, insert molding, overmolding, and post-processing are just a few areas where manufacturers can streamline their operations.
Automated part extraction
Part extraction, also known as part removal, is one of the primary tasks to automate in injection molding. Our robots can quickly and efficiently remove finished parts from the machine and place them on conveyors, in boxes, or in subsequent production steps. This automated handling minimizes the risk of damage to parts, which can occur with manual handling, and speeds up production. Additionally, robotic automation reduces the risk for operators, both because freshly molded parts are often hot and because the risk of injury is high with repetitive tasks.
Insert molding with robots
Insert molding involves placing a pre-made component, such as threads, pins, or other reinforcing details, into the mold before plastic is injected. Since insert molding requires high precision to ensure correct placement of the component, robotic automation is a natural choice. Our robots can easily handle small and complex parts, making the process faster and reducing the risk of errors that could affect the product’s quality.
Overmolding and multi-component products
Overmolding is the process of creating a product by combining two separate molds into a single component. This process is commonly used to produce products with multiple materials or layers. Robots are ideal for this type of application as they can operate at high speeds and ensure precise positioning of parts, resulting in shorter cycle times and higher quality final products.
Post-processing
There are several post-processing steps in injection molding that can be automated to enhance productivity, efficiency, and quality assurance.
Assembly
Plastic components often require assembly to become a finished product. Speed is crucial for assembly, and automation can have an immediate impact on production throughput. Robots are generally faster than humans in assembly tasks, particularly in less complex operations.
Five key factors to consider when automating injection molding
For a successful automation strategy, it is important to select the right solution based on the application, needs, and future production goals. Here are some essential factors to consider:
- Robot type: What type of robot is best for your tasks? Six-axis robots provide maximum flexibility and are suited for complex movements, while cartesian/linear robots are an affordable option for simpler tasks like part extraction and material handling.
- Production requirements: Consider cycle times, speed requirements, and accuracy needs. A fast robot can boost throughput, but balancing this with the need for precision and stability is essential.
- End-of-Arm tooling (EOAT): The right gripper is crucial for safe and efficient part handling. Options include mechanical grippers, suction cups, and soft grippers, each suited to specific material and part types.
- Post-processing and assembly: If your production requires trimming, assembly, or labeling, a robot with the right post-processing capabilities can be essential. Automating these steps enables a smooth, continuous production flow.
- Future-proofing and scalability: Choose a solution that can grow with your future production needs. A flexible robotic solution can be valuable as production requirements increase or change.
