Automated Plastic Injection Molding

In today’s economy, companies are looking to reduce expenses while adding value and quality to their products. Optimize the supply of high-quality affordable plastic components with automated injection molding services from Bruin Manufacturing.

We help clients achieve and surpass production targets while keeping costs down using high-output automated injection molding process lines to produce plastic parts. An ISO 9001:2015-certified manufacturer, our services include prototyping, mold making, welding, assembly and final delivery. With a team of highly trained and knowledgeable engineers on site, we also specialize in product realization and design.

Injection Molding Automation Streamlined Production

Injection molding is a process used to manufacture products by injecting molten material into a shaped mold. When the injected material cools, it retains the shape of the mold and is removed. At Bruin Manufacturing, we utilize emerging robotics and automation technologies in injection molding process lines to reduce costs and shorten lead times, savings that are happily passed on to our customers.

Manufacturing your plastic products on our automated injection lines offers a variety of advantages. Examples include:

  • Improved repeatability
  • Lower manufacturing costs
  • Decreased cycle times
  • Reduced labor costs
  • Enhanced product quality
  • Lessening of waste and variation
  • Increased speed to market

Automation helps make manufacturing more affordable by reducing labor demands. Once the mold is created and processes are finalized, only one operator is needed for control and management. With machines that provide an extremely high degree of precision and quality, production can continue after hours when necessary

Hot-Runner Molding Systems

Bruin Manufacturing utilizes the hot-runner system, which enables our team to meet tight tolerances, offer design flexibility and produce higher quality items than competitors.

In hot-runner systems, the mold is ready to run when the system reaches operating temperature. They enable the use of lower injection pressures, reducing mold and platen deflection and minimizing flash caused by mold component movement.

Hot-runner systems generate better filling and packing conditions than their cold-runner counterparts. When plastic flows through the cold-runner, it loses heat to the mold plates. This can cause pressure drops resulting in sink marks and under-filled parts. Hot-runner systems, however, maintain a balanced melt flow at a constant temperature from the machine nozzle to the gate.

Major advantages to using our hot-runner system include:

  • Balanced melt flow
  • Capable of producing detailed features and complex geometries
  • Elimination of the runner
  • Reduced cycle time
  • Improved molding efficiency
  • Optimal part quality

While hot-runner systems offer a wealth of benefits, they are not suitable for all molding applications. It can be best to keep some parts attached to runners for handling and orientation purposes. We also offer cold-runner services for those designs.

Automated Injection Molding Applications

Production of plastic parts using automated injection molding is quick and affordable. The process is responsible for the creation of products consumers use day in, day out. Examples include:

  • Packaging
  • Fasteners
  • Lids
  • Caps
  • Containers
  • Buckles
  • Instruments

Injection Molding Automation Capabilities 

The use of collaborative robots in injection molding processes helps improve production of plastic parts both tiny and significant, in small batches to large quantities, with precision, speed, and quality.

Whether you have a design already or need one created, we offer a full suite of services to take a product from idea to production, including:

The success of companies relies heavily on supply chain partners. At Bruin Manufacturing, we are dedicated to doing what it takes to meet customer needs on time and within budget.
