Hello, this is HDC.
Today, I'd like to share with you an exciting new perspective on mold repair and spare parts production.
Tool & die shops are a solid foundation of the manufacturing industry, but they face new challenges such as increasingly complex shapes, faster delivery times, and material efficiency.
In this post, we will look at the limitations of the traditional method,
Explore how Meltio's wire-to-laser metal additive manufacturing (AM) technology is going above and beyond.
From complex cooling channels to repairing high-hardness materials, it's packed with insights you can apply directly to real-world manufacturing, so we encourage you to read on!
Molds and dies are at the heart of manufacturing industries worldwide.
It plays an indispensable role in major industries such as automobiles, aerospace, oil and gas, and defense.
It is an essential component for cutting and forming materials with precision and producing high-quality parts.
These parts require increasingly complex shapes, strong materials, and fast delivery times.
However, it is difficult to keep up with these changing demands using existing manufacturing methods.
Metal additive manufacturing (AM), particularly wire-laser directed energy deposition (DED), is emerging as a new solution that disrupts existing methods.
We are fundamentally changing the way we make and repair molds.
Meltio is at the heart of this technological innovation, leading the change.
▶ Mold Design and Machining Companies: The Roots of the Metal Manufacturing Industry
Mold design and manufacturing companies specialize in designing and manufacturing molds and dies used in mass production.
These facilities play a vital role in creating metal components for a wide range of products, from consumer goods to industrial machinery, but their value is often overlooked.
Depending on the purpose of use, molds are manufactured in various forms as shown below.
- Cutting & stamping dies Cutting and stamping dies: Used for mass production by cutting or bending metal plates.
- Drawing dies Drawing die: forming parts by shallow or deep drawing
- Hot stamping molds Hot stamping mold: forming heated metal into a press mold
- Injection molds (plastic or metal) Injection molds (plastic or metal): create complex parts by injecting molten material.
- Extrusion & blow molds Extrusion and blow molding: used for forming hollow shapes such as bottles or continuous profiles.
These processes utilize high-precision milling machines, lathes, wire discharge machines, and grinders, and require high-strength materials that can withstand high temperatures, high pressures, and wear.
▶ Limitations of existing technologies amid fierce market competition
Mold processing companies face increasing pressure:
- Cost and time pressures: Customers want fast, affordable, high-quality parts.
- Tool wear and material waste: Conventional CNC and EDM methods waste expensive materials and have short tool life.
- Complex shapes and custom designs: As component geometries become more complex and designs requiring integrated cooling channels increase, conventional cutting methods are becoming less effective.
- Repair time delay: When dies wear or become damaged, production delays occur, and traditional repair methods are slow and limited.
Shops operating without cutting-edge technology will struggle to meet the growing manufacturing demands and high-value contracts.
[Burden 1: Complex shape and integrated cooling structure]
Problem
Today's molds require intricately designed internal cooling channels. However, conventional machining methods like CNC or EDM struggle to produce these intricate, irregularly shaped structures, resulting in longer cooling times and accelerated mold wear.
Meltio's solution
Meltio's wire-laser additive manufacturing (WAM) allows for the creation of integrated cooling channels directly within the mold, layer by layer, tailored to the design. This allows for the creation of curved, inclined, and near-surface geometries wherever required, and can be combined with copper and steel to improve thermal conductivity and corrosion resistance.
result
- Reduce cooling stage cycle time by up to 80%
- Maintaining even temperature distribution improves product quality
- Reduce cavity corrosion and component defects
Burden 2: High material costs and tool wear
Problem
Conventional mold manufacturing methods waste expensive special steel and require frequent replacement of cutting tools, which increases costs and slows down production.
Meltio's solution
Meltio's additive manufacturing allows for dual-material printing, allowing for high-wear surfaces to be made of high-hardness steel (such as M7) while the interior can be made of ductile, low-cost materials, effectively reducing costs and extending mold life.
result
- Up to 50% material savings
- Reduce CNC machining and tooling costs
- Integrating layering technologies to improve shop productivity
Burden 3: Long lead times and downtime due to wear and tear.
Problem
Damaged molds often require the entire mold to be remade, resulting in delivery delays and inventory burden.
Meltio's solution
Meltio's DED technology can directly restore worn areas, extending tool life without having to replace the entire mold.
result
- Shortened mold restoration time
- Minimize production downtime
- Extending the life of high-wear dies and punches
[Burden 4: Shapes that are difficult to implement with existing equipment]
Problem
Parts that combine different materials or have complex internal structures are difficult to manufacture using standard CNC or casting methods.
Meltio's solution
Meltio's wire-laser AM can be integrated into existing CNC equipment, allowing you to add complex additive processes while maintaining your existing infrastructure.
result
- Possibility of receiving orders for production of high-difficulty parts
- Simplify prototyping and customization
- Improve shop flexibility and profitability
▶ Key Benefits of Meltio's Wire-Laser Metal AM for Mold Processing Companies
The advantages of using Meltio's technology in mold processing companies include:
- Multi-material printing that allows you to use various materials at once
- High precision and reliability
- A system that can operate 24 hours a day
- Even complex shapes can be easily implemented
- Easy for field workers to learn
Wire-laser metal 3D printing is particularly powerful for high-performance mold production that requires cooling performance, precise internal structures, and lightweight designs. When combined with the Meltio M600 and industrial robot integration kits, it can become an optimized mold manufacturing solution for the field.
By expanding design freedom and optimizing materials to improve cooling efficiency, we can not only shorten cycle times but also improve product quality.
In addition to this
- Cost and material savings
- Improving efficiency in rapid prototyping and low-volume custom product production.
- Capable of printing high-durability materials (titanium, copper, aluminum, stainless steel, etc.)
- Minimize material waste
- Cladding work is possible without replacing the entire mold, by repairing only the worn areas.
- Up to 80% cooling cycle reduction
- Increased productivity by reducing maintenance cycles
It has the advantages of the above, and can also implement complex shapes and manufacture parts with multiple material combinations that were impossible with existing cutting methods.
