In 1977, John and Betty Roembke founded Roembke Mfg. & Design.  The company started with a single 2,500 square foot building and a handful of employees that were determined to supply the silicone and rubber industry with the highest quality tools available.  Today the company is led by John’s son, Greg Roembke, is located in a new 62,000 square foot state of the art facility, and has grown in size to over 50 employees.  Roembke Mfg & Design has sustained consistent growth over the last 40 years by treating our customers the same way it treats its employees, like family.

Roembke Manufacturing and Design’s mission is to provide molding solutions to the manufacturing industry that exceed expectations in quality, delivery, and technical capability. We strive to develop long term working relationships with all of our customers while providing our employees with a value added work environment that offers both a highly competitive compensation and a close knit team atmosphere.

Quality is part of our culture, not a separate function. Our technicians are trained and accountable to program and setup the job, know the level of expected quality, utilize proper measuring tools, run the job efficiently, and exceed expectations.

Employees of Roembke take pride in their work, which shows through their ongoing involvement in the search for, development of, and implementation of continuous process improvements.


Liquid Silicone
Rubber Molding Solutions

Roembke Mfg & Design provides the highest level of Liquid Silicone Rubber (LSR) Molds. Our unique mold designs and machining technologies allow for easy mold processing.

We are able to manufacture molds that are capable of producing consistent parts that are as small as 0.007 grams.

Our internal applications center allows us to complete full Factory Acceptance trials (FAT) prior to mold shipment, ensuring that our tools will work the when loaded into a press at your facility.


Roembke Mfg. & Design will design and manufacture state of the art molds for all your High Consistency Rubber (HCR) needs.

We manufacture molds for use in a variety of molding techniques including: Compression, Transfer (with/without Waste Reduction Technology), Injection Transfer, Straight Injection, and Injection with Cold Runner Technology.

All of these tooling options are available with Roembke’s flashless molding technology. And can be tested prior to shipment in our in house applications center.

Tooling options for High Consistency (HCR):

  • Compression
  • Transfer with/without Waste Reduction Technology
  • Injection Transfer
  • Straight Injection
  • Injection with Cold Runner Technology
  • All Tooling Options Allow for Flashless Technology


Roembke Mfg. has developed a unique system to handle your needs for the fast paced turn-around that required during the prototyping stage of development. Our proprietary Quick Prototype System (QPS), allows you to test iterative design and material changes without incurring the typical costs or lengthy lead times associated with building a full production mold or bridge mold.

We have Quick Prototype Systems available for both LSR (Liquid Silicone Rubber) and HCR (High Consistency Rubber) materials. These systems offer a range of advantages of typical molding options. They are compact, versatile, and allow for quick mold changes and setups. All while providing production equivalent parts that allow you to test various material grades, establish shrink rates, compare parting line/gate locations, and a verify automation strategies.


Roembke Mfg. & Design can design, build, and debug cold or hot runner thermoplastic injection molds. This capability allows our customers to single source their thermoset and thermoplastic tooling needs.

The advantages of this simplified sourcing model for our customers include a reduction in required suppliers and can help eliminate many of the difficulties involved with planning projects between multiple plants and facilities.

2-Component Molding is an advanced molding process that can offer many benefits. It can increase throughput while reducing floor space and part rejections.

Roembke Mfg & Design is a leader in this technology. We can offer LSR to LSR or LSR to Thermoplastic 2-Component Molding Cells.

Roembke Mfg & Design also provides tooling for standard over-molding projects. Substrates such as thermoplastic, various metals, glass, and wires are a few examples.
