Mold/Tool Making

Custom plastic molds are widely used in various plastic manufacturing processes. These molds and patterns are precision designed to improve production efficiency. They are widely used during the repeated production of components or parts. Inferior quality molds get damaged easily and they negatively impact plastic production. We regularly design and manufacture custom vacuum forming as well as potting molds for various plastic and electronic applications. At Ehren-Haus, superior quality custom plastic molds are an integral part of producing complex and challenging plastic parts.

Types of Plastic Molds Created

Our plastic mold manufacturing efficiencies allow us to build the following types of molds:

Temporary Molds

These molds are made from materials with a limited service life.  They are less costly than permanent molds and are best suited to be used for small volume low run quantities.

Family Molds

This refers to different molds with many similarities and a few dissimilarities. The molds of this type are widely used by manufacturers who offer products with slight variations. Family molds help manufacturers reduce manufacturing costs.

Permanent Molds

These molds are generally used during high volume production. We can create permanent molds from metals.

Mold and Pattern Making Methods and Techniques Employed

Although plastic is a pliable material, molding plastic sheets is not always easy. It demands technical expertise and technology investments. At Ehren-Haus, we employ the following techniques for plastic mold making.

CNC Routing and Machining

Our experienced machinists employ CNC routing and milling and routing to create precision molds. These molds produced thus standout due to their high quality.  They can be made from medium to high density molding boards of i.e. HD polyurethane as well as metals like aluminum and stainless steel.


When appropriate a mold can be made by pouring a casting material into a hollow shape that matches the basic dimensions needed.  Further machining can be done to achieve the exact mold requirements.

Fixtures & Tooling

Precise tooling and fixtures are critical to repeatability in manufacturing processes.  Molds, CNC machining, casting coupled with assembly when needed are used to create fixtures and tooling. Expertly crafted out of plastics, metals, woods and resin blocks and precise set ups are what makes a fixture and tool successful.  When a fixture and tool is accurate the end result is a correct part or unit.


Industries We Serve

We have worked with the following industries so far.

  • Marine

  • Dept Of Defense

  • NOAH

  • Medical Equipment & supply

  • Retail

  • Refrigeration

  • Museums & Zoos

  • Mortuaries / Medical Examiners

Types of Plastic Materials We Work With

We perform plastic mold manufacturing using the following materials:


Urethane rubber exhibits physical properties such as excellent wear resistance and curability with minimum shrinkage. Urethane molds are suited for production casting of wax, gypsum, and concrete. Urethane material can be brushed, poured, as well as sprayed on prepared surfaces and can be cured easily. Molds made of urethane are available in a broad range of hardness.


We regularly produce epoxy molds in different specifications. Epoxy resins possess several properties such as high strength, minimal shrinkage, and excellent adhesion. The molds made of epoxy are highly durable and reliable.

Other Materials

We can provide molds and patterns made of materials like wood, aluminum, stainless steel and various types of resins.
