Overmolding is a specialized manufacturing process that results in a seamless combination of multiple materials into a single part. Some overmolded seals use a physical bond, while others require a chemical bond. For overmolded seals that require a chemical bond, specialized adhesive coatings are often used due to several key reasons.
In addition to Silicone (VMQ), two materials commonly employed for molding electrical connectors are Liquid Silicone Rubber (LSR) and Heat Cured Rubber (HCR). This article explores the notable qualities of LSR and HCR and their respective uses in automotive gasket manufacturing.
At Morgan Polymer Seals, we perform two critical types of leak testing to help support quality manufacturing for our automotive OEMs: Pressure Decay Testing and Destructive Testing. Here’s a description of both methods, followed by a video that shows leak testing at our manufacturing sites in Mexico.
Compression transfer molding and compression molding are related processes, but they are not the same. However, compression transfer molding can be considered a variation of compression molding with some key differences. Let's clarify the distinctions between these two processes, and watch a video that shows our compression transfer molding process in action.
Elastomer grommets and fastener seals are critical components in automotive design, providing sealing and vibration-damping solutions in various applications. This article explores the definition, applications, benefits, and advantages of elastomer grommets and fastener seals in the automotive industry. Additionally, it presents a selection of high-performance elastomer types commonly used for these purposes.
Elastomer PIP automotive gaskets are specialized sealing solutions designed to provide effective sealing under challenging conditions in automotive applications. These gaskets are typically made of elastomeric materials, commonly known as rubber, which exhibit excellent elasticity, resilience, and chemical resistance.
In this article, we will examine the types of silicone electrical connectors, the manufacturing process, and their application in the automotive manufacturing.
At Morgan Polymer Seals, we manufacture carrier gaskets using a wide range of elastomeric materials, and we use steel, aluminum, or plastic as the carrier "backbone." This article discusses carrier gaskets for automotive manufacturing, including their properties, design considerations, and manufacturing processes.
GM tasked Morgan Polymer Seals to collaborate with ITW to design a mechanical seal for a new capless refueling system in the Cadillac CT6. The custom seal system had to reduce hydrocarbon emissions, seal on the fuel fill-nozzle, and remain flexible at a temperature down to -40°C. This article looks at the design process and how successful seal design is achieved for an automotive application.
A seal’s design has the highest impact on its overall cost and quality, so we enjoy supporting your technical team throughout the entire design process.
Let’s take a look at the timeline and steps involved for the successful design of automotive gaskets and seals.
Here are just a few of the pre-mold, and post-mold capabilities that support the gaskets and seals we manufacture in Mexico.
Compression molding is one of the lowest-cost molding methods with regard to tooling and equipment.
Of significant importance in the effectiveness of the injection molding process are the capabilities of the injection press itself. In this article, we highlight some of the key equipment features that promote satisfactory injection molding for automotive gaskets and seals.
Injection molding is one of the most popular processes for achieving high-quality and cost-effective gaskets and seals.
In this article, we explain the process and its key benefits for precision molding in Mexico.
Some seals are relatively simple, made entirely of rubber. But sometimes a critical system requires sealing components that are more complex than a simple rubber seal.
In these situations, overmolding may be necessary to achieve optimal sealing performance for challenging applications.
In rubber gasket molding, takeover tooling is when an OEM/manufacturer switches to a different supplier and continues using the same tool, or mold, used by their previous supplier to produce the part with a new supplier.
We’re pleased to offer you another technical White Paper, written by our very own Design Engineer, Thomas Morgan. This paper explains how to interpret the results of elastomer analysis in sealing applications.
Morgan Polymer Seals announced today its expansion into markets beyond automotive with new contracts to supply the Ag / Construction and Electric Vehicle segments.
We’re pleased to offer you another technical White Paper, written by our very own Design Engineer, Thomas Morgan. This paper covers the scenarios that are typically required for a proper and complete design process of sealing elastomers.
Morgan Polymer Seals announced today the innovation of its in-house vision inspection technology for a Volkswagen filter plate seal used in a vehicle’s Transmission Electro-Hydraulic Control Module (TECHM).
To coincide with its 25th anniversary, Morgan Polymer Seals announced today a 35,000 square foot expansion of its primary manufacturing plant in Tijuana, Mexico. The expansion, slated for completion on June 1st, will help meet the rapidly growing demand for quality elastomeric seals efficiently manufactured on-shore in North America.
We’re pleased to offer you another technical White Paper, written by our very own Design Engineer, Thomas Morgan. Here are just a few of the key insights you’ll learn gain inside the pages:
Why Finite Element Analysis a critical step in designing quality rubber gaskets and seals

How to work with Approximatation Equations
Vitesco, formerly Continental Automotive, tasked Morgan Polymer Seals to manufacture and deliver T76 filter plates, with the expectation of zero defects. The filter plates feature a black rubber seal design on a black plastic carrier gasket, making defects hard to detect with the human eye.
When automated vision inspection became a much-desired approach to achieving zero PPM, most manufacturers purchased turnkey vision inspection systems to inspect their finished goods. But at Morgan Polymer Seals, we’ve developed our own line of automated vision inspection machines.
Vision inspection is a computer-aided visual analysis of manufactured parts to sort out any with defects, irregularities, or other quality control issues. Unlike manual inspection that relies solely on human hands and eyes, automated vision inspection employs a mechanical system of high-speed cameras, software, and automation hardware components to inspect each part thoroughly and quickly.
General Motors (GM) tasked Morgan Polymer Seals to collaborate with Illinois Tool Works (ITW) to design a mechanical seal for a new capless refueling system in the Cadillac CT6. The custom seal system had to reduce hydrocarbon emissions, seal on the fuel fill-nozzle, and remain flexible at a temperature down to -40°C. To avoid a larger redesign of the car’s body, the sealing system also had to fit within the sedan’s existing size constraints.
Selecting the best raw material for an automotive gasket is paramount to manufacturing a quality seal at a competitive price. An expert seal designer thoroughly understands the key attributes of their polymers and draws from industry experience with automotive systems to select the best material.
Design validation is a critical step to developing a successful gasket or seal. At this stage, a design engineer confirms that the final product will function properly within the sealing application. To validate critical seal designs for automotive applications, savvy engineers have adopted Finite Element Analysis (FEA).
Rubber gaskets and seals are critical components in the mechanical systems for automotive and industrial applications. At Morgan Polymer Seals, we follow these eight stages in the seal design process.
This white paper provides an overview of common molding processes for high-precision gaskets and seals.
