MTI’s Elastomer Injection Molding Services Guarantee Quality, Quantity, and Speed

One of our specializations at Micro-Tronics is elastomer injection molding, a highly efficient process that produces custom-molded elastomer products.

Let’s explore the nuances of elastomer injection molding, including its benefits and what makes it the right solution for your unique project.

Injection Molding Services vs. Other Elastomer Molding Services

Micro-Tronics offers the following custom elastomer molding services:

Injection molding
Compression molding
Transfer molding

While each method is useful in their own ways, our team suggests injection molding services when the customer requires the following:

Large Part Quantities

While compression and transfer molding have their benefits, injection molding comes out on top when it comes to high-volume production.

In our efforts to increase efficiency at all times, MTI decided to add injection molding equipment which allows for more automation and significantly faster cycle times. We also have the ability to increase part density in our tooling and exponentially increase our quantity throughput per cycle. By molding multiple parts per cycle, injection molding maximizes efficiency, making it ideal for projects that require tens of thousands of parts annually.

Second-to-None Precision and Consistency

Injection molding paired with highly engineered and accurately produced tooling delivers precision and consistency. Automated processes ensure that each part meets exact specifications, resulting in uniform dimensions and properties. This level of precision is crucial for industries where consistency is non-negotiable.

Minimal Secondary Processing

Another benefit of injection molding is the potential for minimizing secondary operations. By designing molds effectively, unnecessary trimming and finishing processes can be eliminated, streamlining production and reducing overall costs. This efficiency is particularly valuable for projects with strict budgetary constraints.

Reduced Lead Times

Injection molding offers significantly faster cycle times, making it the preferred choice for mass production. This rapid turnaround ensures that parts are delivered promptly, meeting tight project deadlines and minimizing downtime.

How Micro-Tronics Handles the Design and Production of Mold Tooling

For customers tackling new projects, MTI offers comprehensive mold design and manufacturing services. Our engineering team has decades of elastomer tooling design and production experience. We make sure to take everything into consideration including:

Material properties: shrinkage, curing behavior, and flow properties are taken into account
Part Geometries: complex geometries may require special considerations like draft angles for easy part removal, uniform wall thickness and properly designed venting for air escape
Parting lines and ejector placement: the placement of parting lines and ejectors may have requirements from the customer. We ensure to design around these requirements to ensure the final part has the desired appearance and functionality.
Tolerances and surface finish: Tight tolerances must be maintained and the mold surface finish should align with the required final part finish callouts. We utilize our in-house tooling department to ensure our tooling is up to the task.

Whether it’s a simple or intricate design, we ensure that the resulting mold meets the highest standards of quality and precision.
