According to Future Market Insights, the global thin-wall plastic container market is projected to grow from about $37.4 billion in 2025 to $57.1 billion by 2034, which is an estimated CAGR of 4.8%. This growth is driven by the need for lighter, faster, and more efficient parts across industries like automotive, consumer goods, and packaging.

At Mayco International, we use thin wall injection molding to help our clients meet these demands with precision, speed, and sustainability. In this post, we’ll explain what thin wall injection molding is, how it works, and why it’s a smart choice for your next project.

What Is Thin Wall Injection Molding?

Thin wall injection molding is a specialized process used to create parts with walls that are typically less than 1mm thick. It requires high-speed, high-pressure injection, as well as precise equipment and expert design.

While it’s a more advanced process than standard molding, it offers major benefits when done right.

Key Benefits of Thin Wall Injection Molding

Thin wall injection molding isn’t just about saving material – it’s about making better parts, faster. Here are some of the key benefits this advanced method offers.

Faster Cycle Times

Because the walls are thinner, parts cool and set much more quickly. This means faster production runs and reduced overall lead times. In industries where speed matters, like automotive or consumer goods, this is a big advantage.

Lower Material Use

Thinner parts use less plastic, which cuts down on material costs. At Mayco, we also focus on using recycled and sustainable materials wherever possible. This makes thin wall molding not only cost-effective, but also better for the environment.

Lighter End Products

Thinner plastic parts reduce weight without sacrificing strength when properly engineered. In automotive manufacturing, for example, lightweight parts can improve fuel efficiency and reduce emissions. This aligns with current manufacturing trends aimed at efficiency and environmental impact.

Consistent Quality and Strength

When the design and tooling are precise, thin wall parts are just as strong and reliable as thicker alternatives. Our team uses advanced simulation and testing tools to ensure durability, even with reduced wall thickness.

Challenges and How We Solve Them

Thin wall molding requires exact design, equipment, and process control. Without this, you risk part defects or failed production. That’s why we bring our full engineering and thin wall manufacturing expertise to each project.

We begin with careful material selection. Not every plastic resin is suited to thin wall applications. Our engineers evaluate your product’s purpose and recommend resins that offer the right combination of strength, flexibility, and flow rate.

Next, we design molds with uniform wall thickness and smooth transitions. This reduces the chance of warping or cracking during cooling. Our equipment can deliver high-pressure injection quickly and precisely, essential for thin walls where timing is critical.

These steps, combined with close quality control, help us deliver thin wall parts that meet your specs, your schedule, and your budget.
