Transfer molding, like compression molding, involves preparing raw materials into "pre-forms" that are placed into a "pot" before molding begins. Once the mold is closed, a "plunger" compresses the rubber in the pot, forcing it through channels to fill the cavity.  

Advantages of Transfer Molding Over Compression Molding  

Transfer molding offers several benefits that make it a preferred method for many applications:

Simplified Pre-form Preparation

One pre-form can fill multiple cavities, reducing the need for complex pre-form preparation. This simplified process results in greater efficiency and consistency.

Improved Dimensional Accuracy

Because excess material is held in the pot and not in the cavity parting line, transfer molding enables tighter dimensional tolerances for precision-crafted parts.

Reduced Risk of Contamination for Colored Rubber Parts

Pre-forms can be hand-cut from raw material sheets, which decreases contamination risks compared to mechanical prep methods in compression molding or the use of screws and barrels in injection molding.  

Primary Disadvantage of Transfer Molding  

The main drawback of transfer molding is the increased material waste. Excess rubber left in the pot after transfer is typically cured into a "flash pad," which may require recycling or disposal.

Rubber Injection Molding stands out as one of the most efficient methods for molding rubber, offering an optimized process with numerous advantages. This technique, along with injection-transfer molding, begins with streamlined material preparation to ensure consistency and quality.

The Rubber Injection Molding Process

The process starts with mixing rubber material in 500-pound batches. Once mixed, the material is stripped into continuous strips approximately 1.25 inches wide and 0.375 inches thick. These strips are then fed into a screw on injection molding machines. Here’s a breakdown of the key steps:

Material Preparation and Loading

The screw charges the machine's barrel with a predefined amount of material.

Injection and Curing

When the mold closes, material from the barrel is injected into the mold cavities and cured to create the final product.  

This efficient process ensures consistent material flow and high-quality output.

Advantages of Rubber Injection Molding

Rubber Extrusion Molding offers several key benefits that set it apart from other methods:

Elimination of Pre-Forms

This process removes the need for pre-forms, a labor-intensive step that can lead to variability in weight and shape. By eliminating this step, the final product's consistency improves significantly.

No Operator Placement Required

Unlike compression or transfer molding, operator intervention to place pre-forms in the cavity or pot is not required, making the process faster and more reliable.

Improved Material Flow and Faster Curing

The injection screw pre-heats the material, reducing its viscosity for easier flow into the mold cavities.

The pre-heating and shearing action during injection also decrease curing time, ensuring the process is both efficient and cost-effective.

Rubber extrusion distinguishes itself from molded rubber manufacturing by its unique process. Unlike molding, rubber extrusion involves forcing rubber through a die with the desired cross-section under pressure. Typically, this process uses soft, unvulcanized rubber compounds fed into an extruder. The extrusion process leaves the rubber in a pliable state, necessitating vulcanization (hardening) to create durable, usable products.

The rubber extrusion process

Rubber extrusion occurs over multiple stages designed to produce precision rubber profiles. Here’s a step-by-step breakdown.

Feeding the Rubber Compound

The process starts with feeding a rubber compound into an extruder via a feed hopper. The hopper transfers the material to the flutes of a revolving screw that carries the compound forward.

Moving Toward the Die

The material progresses along the screw, experiencing increasing pressure and temperature as it approaches the die.

Extrusion Through the Die

Upon reaching the die, the built-up pressure pushes the rubber through specific openings in the die. Depending on the rubber compound's composition and hardness, the extruded material may swell to varying degrees. This swelling often necessitates tolerances in the final product's cross-section to meet precise specifications.

Vulcanization and Dimensional Changes

During vulcanization, the rubber undergoes swelling or shrinkage in both its cross-section and length, influenced by the type of rubber compound used. Following vulcanization, extruded rubber may experience dimensional variations, particularly a reduction in the length’s center compared to its ends.

The role of extrusion dies in rubber manufacturing

An extrusion die represents a critical component in creating custom rubber products. Each die is meticulously crafted by cutting an opening into a blank steel piece. The opening aligns with the desired shape of the finished rubber product's cross-section.

When the rubber material is forced through the die by the extruder's revolving screw, some rubber compounds tend to swell. This potential increase in dimensions is considered when designing the die to ensure the final extruded rubber product meets required tolerances. The precise design of the die ensures consistently accurate shapes and dimensions.

The advantages of rubber extrusion

Rubber extrusion offers numerous benefits, making it an ideal manufacturing process for businesses in diverse industries:

Variety of Shapes: Easily create intricate and unique profiles.

Efficiency: Achieve high-quality results at a cost-effective rate.

Flexibility: Lightweight and adaptable for various applications.

Reduced Waste: Efficient use of materials minimizes production waste.

The technique of compression molding has stood the test of time since its humble beginnings in the 1890s, when Harvey Firestone first molded rubber products in his home oven. While technology has advanced, the core principles of compression molding remain largely unchanged. This process involves shaping raw rubber compounds or pre-mixed materials into “pre-forms” that roughly match the final product’s shape. These pre-forms are carefully loaded into open molds, usually by hand, where the mold is closed, the rubber is cured, and the finished part is demolded manually.

Compression molding continues to be a cost-effective solution, particularly in these scenarios:

Existing compression molding tooling eliminates the need for new molds.

Small production runs or low-volume requirements make it an economical choice.

Parts with large cross-sections and lengthy curing times benefit greatly from this process.
