Advantages of Mold-Making Services
Mold making offers significant advantages in terms of cost-effectiveness, precision, flexibility, speed, reproducibility, material versatility, design freedom, and scalability, making it an essential process in mass production.
Cost Efficiency
By using molds, manufacturers can produce parts in large quantities, resulting in economies of scale and reduced per-unit costs. Mold making allows for efficient and cost-effective mass production.
Precision and Consistency
Molds are designed to provide high precision and accuracy in the production of parts. This ensures consistent quality and dimensional accuracy, leading to better product performance and customer satisfaction.
Flexibility
Mold making enables the production of complex and intricate parts with consistent quality. It allows for the creation of parts with various shapes, sizes, and features, meeting diverse customer requirements.
Faster Production
Once a mold is created, the production process becomes faster and more efficient. Molds enable rapid and continuous production, reducing lead times and increasing overall productivity.
Reproducibility
Molds ensure consistent part replication, regardless of the production volume. This makes it easier to maintain quality standards and meet customer demands consistently.
Material Versatility
Mold making supports the use of various materials, including plastics, rubbers, metals, and alloys. This versatility allows manufacturers to choose the most suitable material for their specific application.
Design Freedom
With mold making, manufacturers have the freedom to create complex and intricate designs. Molds can be customized to produce parts with specific shapes, textures, and surface finishes, unlocking innovative design possibilities.
Scalability
Mold making facilitates scaling up production as demand increases. Once a mold is created, it can be used repeatedly to produce large quantities of parts, ensuring scalability and efficient growth.
Mold-Making Process
Mold making is a complex process that requires a high level of skill and experience. Although each case is different, a typical order for a set of molds may go something like this:
DFM
As soon as the customer confirms the order of molds, we will initiate a preliminary analysis of the parts to gain an understanding of the parting line, gate positions, and other crucial factors.
Mold design and mold flow analysis
The second step involves leveraging predictive modeling software, enabling us to simulate and visualize the behavior of the molten material as it enters the mold. This empowers us to make informed design refinements and enhancements.
CNC machining and EDM
We fabricate the initial molds using top-notch machining equipment, ensuring precision and quality. The choice of plastic, steel, aluminum, etc. for the molds is tailored to meet the specific preferences and requirements of the customer.
T1 sample
With the newly made molds, we make a T1 sample to have a clear vision of how the customer’s final molded parts will turn out.
Improvement if necessary
Based on our analysis of the T1 sample, we review the mold design and make any adjustments needed.
Commence production and shipping
We manufacture the molds in accordance with the final specifications before shipping them to the customer.
Types of Molds We Made
There are several mold-making processes used in the manufacturing industry. The choice of process depends on factors such as the type of material, complexity of the part, production volume, and desired level of precision.
Plastic Injection Mold
Plastic injection molds are aluminum or steel molds used to make parts from a wide range of plastics, including nylons, acrylics, elastomers and reinforced materials like glass-filled polyamide. Custom plastic molds can last between 100,000 and 1,000,000 shots.
Metal Injection Mold
Metal injection molding (MIM) is a form of injection molding where a metal and binder mix is used as feedstock. A metal injection mold is usually made from tool steel to withstand the metal injection, but we can also use aluminum.
Die Casting Mold
Unlike many prototyping specialists, we can provide metal casting molds (and a low-volume casting service through our partners). These molds — typically made from hardened steel — can be used to make parts from aluminum, zinc, magnesium and other non-ferrous metals.
Investment Casting Mold
We can make low-cost investment casting molds by 3D printing a wax pattern and surrounding it with ceramic. The ceramic molds can then be used to make metal cast parts from metals like aluminum, zinc, magnesium, stainless steel and more.
Extrusion Mold
Our metal die molds can be used for aluminum extrusions of alloys like 6061 and 6063. We also make molds for plastic extrusions of materials like polystyrene, nylon, polypropylene and polythene.
Sheet Metal Mold
Our experience making sheet metal molds for stamping and bending allows us to create sheet metal prototypes.
Mold-Making FAQ
What is mold making and when do you need it?
Molds are normally created to duplicate plastic and metal parts. After testing the prototypes and the market, it is the most cost-efficient way to launch your products at scale.
Should I choose a locally produced mold or an exported mold?
Generally speaking, making plastic or metal molds (and moldings) is cheaper in China than other countries. But shipping costs should also be considered: you will need to use air freight if you have a tight schedule; sea freight is much cheaper, but will usually take 40 days or more.
How long does a mold last?
A well-made, fully harden steel mold may be used for up to a million shots or injections, depending on the mold shape and injection material. Aluminum molds are less durable, which is good for short-run production with tight schedule.
Can molds be any shape?
Molding designs should avoid sharp corners, inconsistent wall thicknesses, and other features that restrict material flow.
When do I need full automatic mold?
Whatever you decide to use, in the end, what is the best cost-efficient way to get your parts done in the required quality is the key.
