What is Tool Steel for Mould Making
Tool steel is a type of high-hardness, abrasion-resistant steel, specifically engineered to withstand intense wear and stress, making it an ideal choice for mould making. Its unique properties allow it to maintain sharp edges and endure heavy pressure, heat, and repeated usage. Tool steels are commonly used for creating dies (stamping or extrusion), cutting tools, injection moulds for plastic parts, and other industrial tools requiring high precision.
For companies needing moulds for manufacturing plastic parts, tool steel for mould making is the standard choice. However, not all tool steels are the same, and recent advancements offer a range of specialized options tailored to different applications and industry needs.
What is the Best Tool Steel for Mould making?
Selecting the best tool steel for mould-making depends on factors such as application type, production volume, part complexity, and the material being moulded. Each type of tool steel offers unique properties suited to specific requirements. Here’s a look at some commonly used tool steels for mould making and the applications they best support.
General Purpose Tool Steel
P-20: P-20 is one of the most popular choices for general-purpose injection moulding. It offers a balanced combination of wear resistance, toughness, and machinability, making it a versatile option. P-20 is suitable for a wide range of applications, including moderate-volume production, and is relatively cost-effective compared to other tool steels. This steel is often chosen for moulds that don’t require extreme hardness or high resistance to abrasion, making it a practical choice for many manufacturers.
High-Performance Tool Steels
H-13: For high-volume production and complex parts, H-13 is a high-performance tool steel known for its excellent wear resistance and toughness. It can withstand higher temperatures, making it ideal for moulds that experience a lot of heat, such as those used for producing high-temperature plastics or materials with abrasive additives. This makes H-13 a common choice for manufacturers needing moulds that will hold up under intense conditions, ensuring long-lasting durability and high-quality production.
S-7: S-7 tool steel is recognized for its high strength and exceptional toughness, which makes it ideal for large, complex moulds that require both precision and durability. S-7 can handle repeated impact and wear, so it’s often used in moulds for parts with intricate shapes or tight tolerances. Additionally, its high toughness allows it to resist cracking or breaking under heavy stress, making it a preferred choice for large moulds in industries requiring detailed, high-quality parts.
Corrosion-Resistant Tool Steel
420 Stainless Steel: In applications where corrosion resistance is essential, such as medical or food-grade products, 420 stainless steel is an excellent choice. It’s commonly used for moulds exposed to corrosive materials or frequent cleaning processes. In addition to corrosion resistance, 420 stainless steel offers good wear resistance, which helps extend the life of the mould in high-humidity or aggressive production environments. Its resistance to rust and cleanliness make it ideal for industries where hygiene and durability are critical.
How to Select the Right Moulds with the Right Tool Steel for Plastic Products Manufacturing
Selecting the right tool steel for plastic injection moulds is essential to ensure durability, cost-effectiveness, and quality. Different factors, such as the type of plastic, part complexity, production volume, required finish, and budget, all influence the ideal choice of tool steel for mould making. By carefully considering these aspects, companies can select the best tool steel for their specific needs and produce high-quality plastic products more efficiently.
Here’s a breakdown of the key factors to consider when selecting tool steel for mould making in plastic products manufacturing:
Plastic Material
The characteristics of the plastic material being moulded play a major role in choosing the right tool steel. Here are some material-specific recommendations:
Abrasive Plastics: Plastics that contain glass fibers, mineral fillers, or other abrasive materials require high wear-resistant tool steels. H-13 and D-2 are excellent choices for these types of plastics, as they resist wear and prevent premature mould wear, ensuring consistent quality over time.
Corrosive Plastics: If the plastic material is corrosive, like PVC or certain engineering plastics, it’s essential to choose corrosion-resistant steels. 420 stainless steel or P-20 with a specialized surface treatment are well-suited for these applications, as they prevent corrosion damage and extend mould life in aggressive environments.
High-Temperature Plastics: For plastics that require high temperatures, tool steels with good heat resistance are essential. H-13 and D-2 provide excellent durability at high temperatures, making them ideal for injection moulds handling heat-resistant plastics.
Part Complexity and Tolerances
The complexity of the part design and the required tolerances are also critical in tool steel selection:
Simple Parts: For straightforward parts with minimal complexity or loose tolerances, general-purpose steels like P-20 are cost-effective and sufficient. These moulds are easier to machine and require less processing time, which is suitable for simpler designs.
Complex Parts: For parts with intricate designs, tight tolerances, or detailed features, high-performance steels are preferable. H-13 and S-7 are excellent choices for complex moulds, as they offer high strength and precision, enabling the mould to retain complex shapes and fine details without degrading over time.
Production Volume
The anticipated production volume significantly impacts the choice of tool steel.
Low-Volume Production: For low-volume production runs, where the mould will not experience high wear, cost-effective options like P-20 may be ideal. P-20 is durable enough for smaller production quantities and is more affordable, making it a practical choice for companies aiming to minimize costs.
High-Volume Production: For large-scale production, durability and wear resistance are essential to avoid frequent mould replacements. H-13 and D-2 are highly durable and wear-resistant steels that perform well in high-volume manufacturing, maintaining mould integrity even with frequent cycles.
Required Surface Finish
The quality of the final product’s surface finish depends on the polishability of the tool steel used:
High-Quality Finish: Tool steels with high polishability are crucial for products requiring a premium surface finish. P-20 and S-7 both have excellent polishability, enabling a smooth, high-quality surface that enhances the visual appeal and functional performance of the moulded parts.
Cost Considerations
Cost is often a critical factor in tool steel selection, particularly for companies with budget constraints. Tool steels vary widely in price, and different mould applications may not require the highest-grade material. Consider the following:
Budget Constraints: For lower-budget projects, P-20 steel offers a balance of cost and performance. This makes it ideal for lower-cost applications that don’t require extreme durability. It is also suitable for moulds used in low-volume or less demanding applications.
Higher Investment for Long-Term Performance: For moulds that require exceptional durability and resistance to wear, investing in steels like H-13 or D-2 might be cost-effective in the long run. These steels have a higher initial cost but reduce maintenance and replacement expenses over time.
