Materials for Injection Mold

Tool Steel

Before starting the injection molding process for either low or high-volume production, precise CNC-machined tooling is essential. The tooling is typically made from high-tolerance materials like tool steel to ensure durability and accuracy. Commonly used tool steel.

Types include P20, H13, S7, NAK80, S136, S136H, 718, 718H, and 738.

Stainless Steel

Injection molds are created from steel and stainless steel, which are costly to manufacture. Due to their expense, these molds are typically used only in large-scale productions.
Types: 420, NAK80, S136, 316L, 316, 301, 303, 304

Aluminum

Aluminum molds are significantly more affordable than traditional steel and carbon steel injection molds. They provide faster cycle times and quicker turnarounds, making them ideal for testing markets and accelerating product development.

Plastic Injection Molding Process

Plastic injection molding is a highly efficient and versatile process used to produce complex and intricate plastic parts through the following steps

Mold Design & Material: Molds are precision-designed using CAD software, typically crafted from steel for durability or aluminum for faster cooling, depending on production requirements.
Plastic Preparation: Specific plastic granules are selected based on desired product properties, then dried and loaded into the machine’s hopper.
Melting & Injection: The plastic is melted and injected into the mold under high pressure, ensuring complete filling and accurate detailing.
Cooling & Solidification: The molten plastic cools and solidifies within the mold, aided by precisely controlled cooling channels to minimize defects.
Ejection & Finishing: The solidified part is ejected from the mold and may undergo trimming, polishing, or painting for final finishing.
Quality Inspection: Each part is inspected to ensure it meets all required specifications for dimensions, appearance, and performance.

Advantages of Prototype Tool

Prototype tooling is crucial for efficient product development, providing a cost-effective and quick route from design to functional prototype. Its key advantages include:

Speed to Market: Accelerates development and refinement, shortening the time to launch.
Cost Efficiency: More affordable than full-scale molds, reducing initial investment.
Design Flexibility: Allows easy modifications based on testing feedback.
Risk Reduction: Identifies potential production issues early, preventing costly future corrections.
Functional Testing: Enables thorough testing to ensure the product meets all requirements.

Injection Mold Tooling FAQs

Why is Injection Molding Tooling So Expensive?

Injection molding tooling costs are high for various reasons.

Material Costs: Molds are typically made from high-quality, durable materials like hardened steel or aluminum. Steel is particularly costly but necessary for long production runs due to its durability.

Complex Manufacturing Process: Producing molds involves precise and labor-intensive processes, including CNC machining, EDM (Electrical Discharge Machining), and sometimes hand polishing. The complexity of the mold, including multiple cavities, undercuts, or intricate details, adds to the cost.

Precision: High-precision molds are essential for producing parts with tight tolerances, especially in industries like automotive, aerospace, or medical. Achieving this level of precision requires advanced manufacturing equipment and skilled technicians, which increases the overall cost.

Customization: Injection molds are custom-built for specific products, and each design demands unique considerations. This custom nature of the tooling, tailored to individual part requirements, significantly raises costs compared to more standard, off-the-shelf tools.

Design and Engineering Time: Developing a mold requires significant design work to ensure it can withstand high pressure and temperature during the injection process. The design must also account for part geometry, cooling channels, and ejection systems, requiring specialized engineering expertise.

What Factors Influence Injection Mold Tooling Design?

Several factors affect the design:

Part Design and Geometry: The shape, size, and complexity of the part being molded greatly influence the mold design. Complex geometries, intricate details, and thin walls require specialized mold features, such as additional cooling channels or more advanced gating systems.

Material Selection: The plastic type significantly impacts mold design, affecting factors like cooling rates, shrinkage, and flow behavior. For example, polypropylene shrinks more, while polycarbonate requires higher mold temperatures. The mold material must also resist wear from abrasive or corrosive plastics.

Tolerances: Tolerances and Precision Requirements: High-precision parts require molds with tighter tolerances, which can complicate the design and increase manufacturing costs. Mold designers must account for dimensional accuracy and consistency, particularly in industries like automotive and medical.

Ejection System: The method of ejecting the part from the mold affects both mold design and cycle time. Options like ejector pins, air blast systems, or stripper plates must be carefully integrated into the mold to avoid damaging the part.

Gate Design: The location and type of gate (direct, pin, or edge gate) determine how the molten plastic enters the mold. Gate design affects the quality of the finished part, influencing flow characteristics, surface finish, and cycle time.

Undercuts and Parting Lines: Parts with undercuts or complex geometries may require side actions or lifters in the mold design to release the part without damaging it. These features increase mold complexity and cost.
