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.

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.

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:

• Product design
• Mold making
• Material selection
• Manual and automated assembly
• Ultrasonic welding
• Secure, custom packaging
• Gain a competitive advantage

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.
