Soft Tooling vs. Hard Tooling

“Soft tooling” and “hard tooling” describe different approaches to creating molds, dies, or tools for producing parts. These terms refer to the materials used in making the tooling and have significant implications for cost, production volume, and lead times.

This article explores the differences between soft tooling and hard tooling, with a particular focus on how they apply to injection molding. However, the concepts are broadly applicable across various manufacturing technologies.

What is Soft Tooling?

As the name suggests, soft tooling involves using softer materials, such as aluminum or urethane, to create molds or dies. These materials are easier to machine, quicker to produce, and less expensive than the hard steels used in hard tooling. However, the trade-off is reduced durability and a shorter life span.

Material: Typically made from aluminum, urethane, or other relatively soft materials.

Cost: Lower upfront costs due to the ease of machining and less expensive materials.

Production volume: Ideal for low to medium production volumes, prototyping, and short-run production.

Lead time: Faster tooling production due to easier machining and faster turnaround times.

Durability: Lower durability means the tooling wears out faster, especially when used with harder materials or high production volumes.

Soft tooling is often used when flexibility is required, such as in prototyping, where designs may change frequently, or in short-run production, where the investment in complex tooling cannot be justified.

What is Hard Tooling?

Hard tooling uses hardened steel or other durable materials to create molds, dies, or tools. These materials are much stronger and are designed to withstand the rigors of high-volume production.

Material: Made from hardened steel or other durable materials.

Cost: There are higher upfront costs due to the complexity of machining harder materials and the longer production time required.

Production volume: This is ideal for high-volume production runs, where the cost per part can be amortized over a large number of units.

Lead time: Tooling production has longer lead times due to the complexity of machining and the toughness of the materials used.

Durability: Extremely durable, suitable for producing thousands to millions of parts with consistent quality.

Hard tooling is the go-to option for large-scale production, where the high initial investment is offset by the tooling’s longevity and the low cost per part.

Deciding Between Soft and Hard Tooling

The decision between soft and hard tooling depends on several factors, including production volume, budget, lead time, and the nature of the parts being produced.

Production volume: If your project requires a high volume of parts, hard tooling is typically the best choice due to its durability and lower cost per part in large runs.

Budget: Soft tooling is a more economical option with quicker lead times for projects with tight budgets or those in the prototyping stage.

Lead time: If the project demands a fast turnaround, soft tooling offers the advantage of quicker production, allowing for more rapid iterations and adjustments.

Part complexity: Complex parts with intricate details may benefit from hard tooling, which can maintain tight tolerances over many cycles. However, if changes are anticipated, starting with soft tooling might be wiser.
