Selecting the Right Tool Steel for Plastic Injection Molds
Choosing the right tool steel for a plastic injection mold involves considering various factors, such as the type of plastic being molded, the design of the mold, the expected production volume, and the desired characteristics of the final product.
The Society of the Plastics Industry (SPI) categorizes mold tooling into five classes: Class 101 to Class 105. Each class is defined by specific requirements, largely influenced by the anticipated production volume. These classifications help guide the selection of materials, including tool steels, to ensure optimal performance and durability based on the project’s needs.
SPI Mold Classifications: 5 Injection Mold Standards
| Standards | Lifetime Cycles | Production level | Steel Hardness | Wear Resistance | Thermal Conductivity | Cavity Steel |
|---|---|---|---|---|---|---|
| Class 101 | 1 million or more | Extremely high-volume | 50~54 HRC | Very High | High | S7,H13 |
| Class 102 | Not exceeding 1 million | High-Volume | 48~52 HRC | High | Moderate | S136, 2344 |
| Class 103 | Not exceeding 500,000 | Medium Volume | 38~42 HRC | Moderate | Moderate | 2738, 718, 718H, NAK80 |
| Class 104 | Not exceeding 100,000 | Low-Volume | 15~25 HRC | Low | Low | S50C, P20 |
| Class 105 | Not exceeding 500 | Very low | Below 15 HRC | Very low | Very low | Aluminum |
Breakdown of SPI Mold Classes
Here’s an overview of each mold classification in the Society of the Plastics Industry (SPI) system, which helps guide the selection of tool steels for plastic injection molds:
- Class 101: Designed for the highest production volumes, this category is used for large-scale manufacturing. Molds are built to withstand continuous use in mass production environments.
- Class 102: Suitable for medium to large production runs, these molds are tougher and more corrosion-resistant, capable of handling significant production but with less intensity than Class 101.
- Class 103: Designed for medium production runs, these molds are built with higher precision, ideal for applications that require parts with superior accuracy and quality.
- Class 104: Used for low to mid-range production runs, these molds offer versatility, making them suitable for jobs requiring various options or adjustments during production.
- Class 105: Tailored for the smallest production runs, these molds are built with flexibility in mind, ideal for short runs or prototyping where frequent changes may be needed.
Keep in mind that the SPI classification system is a general guide, and molds may sometimes fit between categories. The choice of mold class depends on your specific requirements, including the type of plastic, mold design, and production volume.

What is the Injection Mold-Making Process?
The entire injection mold creation process includes steps from initial design and prototype development through to finalizing the mold for transfer to production or packaging and shipping directly to the customer.
To manage each phase, the Mold Process Production Schedule helps keep track of timelines and progress.
Producing an injection mold is a detailed process with multiple stages to ensure the final mold can generate high-quality plastic parts. Here’s a summary of each step:
Design and Prototyping
- Develop a 3D model of both the mold and part using software like UG or PROE.
- Make a prototype to test functionality, allowing for any needed design adjustments.
Mold Design
- Outline the mold’s internal structure, such as cooling channels, cores, alignment guides, ejector pins, and cavities.
- Confirm that the design aligns with required specifications and tolerances.
Material Selection
- Choose the mold material (e.g., hardened steel or mild steel) based on the needs of the part and intended production volume.
- Consider durability, corrosion resistance, and thermal conductivity when selecting materials.
Machining
- Machine the chosen material using precision techniques like CNC machining or EDM.
- Create the mold’s internal details, including cavities and cores.
Assembly and Installation
- Assemble the mold by fitting inserts, cores, and ejector pins accurately.
- Ensure proper fit and alignment of all parts within the mold.
Inspection and Testing
- Inspect the mold for any defects, ensuring it meets quality standards.
- Test mold functionality, including the ejection and cooling systems, to confirm part quality.
Quality Control
- Perform multiple tests to verify the mold’s adherence to specifications.
- Check mold performance, including part dimensions and appearance.
Packaging and Shipping
- Carefully pack the mold to prevent damage during transport.
- Ship the mold to the intended destination.
Additional Process Steps
Some optional steps might be included during the mold-making process:
Surface Treatment: Apply surface treatments like chrome plating or nitriding to improve mold strength and rust resistance.
Coating: Use coatings such as release agents or lubricants to simplify part ejection and minimize wear.
Mold Maintenance: Provide maintenance guidelines to customers to ensure mold longevity and optimal performance.
The exact process can vary depending on the mold maker, mold type, and customer requirements.
How Long Can an Injection Mold Last?
With proper upkeep, an injection mold’s lifespan generally falls within these ranges:
- High-volume production (100,000–500,000 parts/year): 1 to 3 years
- Moderate-volume production (50,000–100,000 parts/year): 3 to 5 years
- Low-volume production (10,000–50,000 parts/year): 5 to 10 years or more
What Impacts the Lifespan of Injection Molds?
Several factors influence how long an injection mold will last:
- Design and Quality: A mold crafted with precision and quality materials outlasts one that is poorly made.
- Production Volume and Frequency: Higher usage means more wear and a shorter replacement cycle.
- Material Choice: Stronger materials, such as steel, extend mold life compared to softer options like aluminum.
- Maintenance and Cleaning: Routine maintenance and cleaning enhance a mold’s durability.
- Operating Environment: Exposure to high temperatures, pressures, or corrosive elements can reduce mold longevity.
Maintenance and Cleaning: Regular cleaning and maintenance will make a mold last longer.
Operating Conditions: Extreme temperatures, high pressures, or corrosive environments will shorten a mold’s lifespan.
Four Strategies to Extend Injection Mold Lifespan
Regular Cleaning and Maintenance
Consistent cleaning and upkeep are essential for keeping molds in top condition. Investing in quality cleaning products can remove buildup effectively, ensuring the mold remains in excellent shape and produces high-quality parts.
Implement an Effective Cooling System
Since injection molding involves high temperatures, efficient cooling allows the molded part to solidify and safeguards the mold. Without proper cooling, parts may deform, and the mold’s durability could be compromised.
Select High-Quality Mold Steel
Using premium steel extends the life of a mold. While cheaper materials might reduce upfront costs, they often lead to shorter mold life and less reliable output. Investing in durable steel results in longer-lasting molds and improved product quality.
Invest in Automation
Automation helps minimize human error, preserving mold integrity. Repeated use of automated processes also reduces mold wear, allowing them to last longer when producing consistent parts.
