Looking at the New Industry Opportunities Behind Home Appliance Mold Manufacturers

Injection molds come in various types, each designed to meet specific manufacturing needs and part complexities. Here's a detailed look at the primary classifications:

1. Single-Parting-Line Injection Mold
When the mold opens, the cavity and the core separate to eject the plastic part. This type is called a single-parting-line mold, also known as a two-plate mold. It is the simplest and most basic form of injection mold. Depending on requirements, it can be designed as a single-cavity or multi-cavity mold. It is the most widely used type of injection mold.

2. Double-Parting-Line Injection Mold
The double-parting-line injection mold has two parting lines. Compared to the single-parting-line mold, it includes an additional movable intermediate plate (also called the runner plate) in the core section. This plate contains the gate, runner, and other necessary components, hence it is also called a three-plate mold (moving plate, intermediate plate, and fixed plate).
It is commonly used for single-cavity or multi-cavity molds with point gates. During mold opening, the intermediate plate separates from the fixed plate at a fixed distance along the guide pillars to allow the removal of the runner system. The double-parting-line mold has a complex structure, higher manufacturing costs, and difficulties in machining parts, making it unsuitable for large or extra-large plastic products.

3. Injection Mold with Side Core-Pulling Mechanism
When the plastic part has side holes or undercuts, a laterally movable core or slider is required for molding. After injection, the moving mold first moves downward a certain distance. Then, the inclined surface of the angled pin fixed on the fixed plate forces the slider to move outward. Simultaneously, the ejector pins of the demolding mechanism push the ejector plate to release the part from the core.

4. Injection Mold with Movable Molding Components
Due to special structural requirements of the plastic part, the mold may need movable components such as movable cores, movable cavities, movable inserts, or threaded cores/rings. These components can move out of the mold with the part during ejection and then be separated from the part.

5. Automatic Thread-Removing Injection Mold
For threaded plastic parts requiring automatic demolding, the mold can be equipped with rotatable threaded cores or rings. The mold opening action, the rotation mechanism of the injection machine, or a dedicated transmission device drives the rotation of the threaded core or ring to release the part.

6. Runnerless Injection Mold
The runnerless injection mold uses methods like insulated or heated runners to keep the plastic in a molten state from the injection machine nozzle to the cavity. This ensures no runner system is ejected with the part. One of these molds is called an insulated runner mold, while the other is called a hot runner mold.

7. Right-Angle Injection Mold
The right-angle injection mold is only suitable for right-angle injection machines. Unlike other molds, the feeding direction is perpendicular to the mold opening/closing direction. The main runner is located on both sides of the parting line of the cavity and core, and its cross-sectional area usually remains constant. To prevent wear and deformation at the nozzle and runner entrance, replaceable runner inserts can be used.

8. Injection Mold with Ejection Mechanism on the core
In most injection molds, the ejection device is installed on the cavity side to align with the ejection system of the injection machine. However, due to the shape limitations of some plastic parts, it is better to keep the part on the core side. In such cases, an ejection mechanism must be installed on the core side to release the part.

Plastic injection molding plays a crucial role in many industries. You might find that the plastic casing of your TV remote, the dashboard in your car and the covers on your phone were all made using this process. If you\re a part of the industry or just starting to learn about it, you might have wondered: What is the average lifespan of a plastic injection mold?

It's a wise question to ask, since molds can be very expensive. Some good molds can be extremely expensive, running into thousands of dollars. That's why it's important to know how long you can use one part before it starts to show wear.

Let's take a step back and look at this in a straightforward way. We'll go over the factors that influence the life of a mold, the number of parts you can produce, how to maintain it and how to make it serve you for a longer time.

What Is a Plastic Injection Mold?

Before talking about mold lifespan, we need to answer the question, what is mold?

A plastic injection mold is made to mold melted plastic into a particular shape. Most of them have two sides that come together and clamp tightly. Melted plastic is injected into it under pressure, cooled, and then the mold opens to eject the final product.

These molds may be tiny for bottle caps or huge for car bumpers, but each one is made to serve the same purpose: making parts fast and repeatedly.

How Long Does a Mold Last?

Here's a general guideline to help you better understand the difference.

• Prototype molds: Most prototype molds can produce parts for a few hundred to a few thousand cycles.

• Production molds: The lifespan ranges from 100,000 to 1 million cycles, based on a variety of conditions.

In some cases, with excellent care and the right materials, molds have lasted for more than 2 million cycles. But that's the high end, not the norm.

Let's dig deeper into what affects that lifespan.

Factors That Affect Mold Life

A plastic injection mold's lifespan can vary greatly depending on a variety of elements that can either help it last longer or reduce its service life.

1. Mold Material

You can't expect every mold to last the same amount of time. The type of material chosen has a major impact on how long the mold will hold up.

• Aluminum molds are less expensive and easier to create. They are ideal for testing and limited production but have a short lifespan.

• Steel molds—especially hardened tool steel—are built for high-volume production and long-term durability.

If you're aiming for millions of parts, steel is your best bet.

2. Plastic Type Used

Some plastics are easier to mold than others. Some are smooth and easy-going. Some plastics are abrasive and will slowly eat away at your mold if you're not careful.

For example:

• Glass-filled plastics are tough and can cause faster wear.

• Abrasive or corrosive materials like PVC or fiberglass-filled compounds can chew up even high-grade steel if not managed well.

3. Part Design Complexity

When parts are complicated, the mold needs to have moving parts such as sliders, lifters or inserts. As molds get more complicated, there is a higher risk of damage.

A simple divided mold with simple shapes works much better in the long run than one that moves and shifts its own parts all the time.

4. Molding Conditions

How the machine is set up also matters. Poor temperature control, improper clamping force, or using excessive injection pressure can slowly damage the mold.

Like any tool, if you misuse it, it breaks faster.

5. Maintenance and Cleaning

This is a big one. Regular mold maintenance can make a world of difference. If a mold is cleaned, lubricated, and inspected after every production run, it'll last much longer.

Neglect it, and problems pile up quickly.

Average Lifespan Based on Use

To make things more practical, here's a rough idea of what you might expect based on the type of mold:

Note: "Shots" refers to the number of times plastic is injected into the mold. One shot can produce one or more parts.

Common Signs of Mold Wear

Molds don't just stop working overnight. There are usually early signs that it's wearing out.

Watch out for:

• Rough or uneven part surfaces

• Flash (extra plastic around edges)

• Poor fit between mold halves

• Sticking or ejection issues

• Slower cycle times

Spotting these signs early means you can fix the mold or refurbish it instead of replacing it entirely.

How to Make Your Mold Last Longer

Keeping your mold in good shape reduces costs and ensures your production line does not slow down. Let's go over a few suggestions to boost your mold life:

1. Use the Right Mold Material

For a high volume of jobs, avoid using cheap aluminum molds. You might save some money at first, but the cheap option will cost more when it stops working in the middle of your project.

Although steel molds have a higher initial cost, they save money over time.

2. Match Plastic and Mold Carefully

If you're using abrasive materials, use coated steel or stainless steel for better resistance. Also, avoid over-processing the plastic, as high temperatures and shear stress can damage both the plastic and the mold.

3. Stick to Recommended Molding Settings

Avoid pushing the machine beyond its limits. High pressures and temperatures may get you faster cycles, but they're hard on the mold.

Find the sweet spot between efficiency and longevity.

4. Routine Maintenance is Key

This can't be stressed enough. After each production run, clean and inspect the mold. Look for early signs of wear. Check vents, cooling lines, pins, and seals.

Replace worn-out parts before they lead to bigger issues.

5. Store Molds Properly

When not in use, store molds in a dry, temperature-controlled space. Use rust inhibitors if needed, especially for steel molds.

Can Molds Be Repaired or Refurbished?

Absolutely. If a mold shows signs of wear, it doesn't always mean you need a brand-new one.

Common refurbishing options include:

• Re-polishing cavity surfaces

• Replacing worn-out ejector pins or sliders

• Welding small cracks or chips

• Resurfacing key contact areas
  
  

Regular servicing can extend mold life significantly and keep production costs down.

How Industry Standards Define Mold Class

When it comes to injection molding, molds are categorized according to their ability to withstand use and what they will be used for. According to the SPI, the standard types of molds are Class 101, Class 102, Class 103 and Class 105. For instance, molds from Class 101 are designed for producing huge quantities and are crafted using the highest quality materials and coatings.

Alternatively, Class 105 tooling is only designed for a few uses, mainly prototypes and has a cycle life that is less than 500. With this knowledge, manufacturers can select molds that support their objectives and work within their budget.

Cost vs. Lifespan – What's the Balance?

Let's be honest, molds are not cheap. So, naturally, businesses try to get the most out of their investment. But trying to stretch a mold beyond its limits without care usually ends up costing more in defective parts, downtime, and emergency repairs.

Instead, choose the right mold material for the job and follow proper maintenance. That way, you'll get the best of both worlds: long life and smooth production.

Here's a basic guide:

Conclusion

A plastic injection mold may be used for hundreds of cycles or up to several million.
