What You Should Know About Anodizing Aluminum

When using metal components or creating products made from metal, anodizing can be a valuable step in the process, especially with a softer metal like aluminum. The process of anodizing aluminum prevents corrosion, resists scratching, improves aesthetics and creates a more durable product. The following information will help you see the value in completing this process for your metal components.

How Does It Work?

Before anodizing aluminum, the metal is first cleaned to remove any debris on the surface. It is then placed in an electrolytic solution and a positive electric charge is administered directly to the aluminum while a negative charge is sent to plates suspended in the solution. Negative ions are then pulled toward the aluminum.

What Is the Barrier Layer?

During the process in the electrolytic solution, pores on the aluminum open up to let the positive ions out, creating a geometric pattern that erodes into a substrate. The surface of the aluminum bonds with O2 to create aluminum oxide, creating a barrier that protects against corrosion and other chemical reactions. The longer the process continues, the pores extend deeper into the aluminum. Non-hard anodized coatings typically measure about 10 microns. Once the desired depth is reached, a cold water rinse stops the process.

Hard Anodizing

If you need greater corrosion protection for your aluminum, hard anodizing is the right solution. To achieve hard anodizing, a longer barrier process is necessary, often reaching depths of 25 microns or more. While this process takes more time and can be more costly, it provides enhanced durability to the metal.

Is Corrosion Protection Necessary?

Aluminum doesn’t rust, so you may wonder if corrosion resistance is even necessary. The answer is yes. While it can’t rust, aluminum can experience oxidation when exposed to the air. This oxidation is relatively harmless to aluminum, but that’s only when you consider exposure to pure air and water. In the real world, aluminum may be exposed to salt water, acid rain and other contaminants that can have a negative impact on the metal, making corrosion protection a necessity to avoid discoloration or mechanical failure.

Adding Color to Anodized Aluminum

When most people think of anodized aluminum, they think of coloring, which is a common use for the process. Once you have created the pores with the anodizing process, it’s the perfect time to add color to the metal before sealing off the pores with a water rinse. Adding color to aluminum using this process ensures long-lasting color. Because it lies deep within the metal, it won’t scratch off the surface.

Creating the Popular Metallic Look

When you think of something metal, you often think of something shiny. This is the result of the anodizing process. Anodizing is a form of etching that leaves the surface of the metal with a rough texture. Deeper pores mean a rougher texture. The way the light bounces off this surface creates the tell-tale metallic sheen most people recognize.

Use Caution with Your Design

When creating your anodizing bath, it’s important to remember it’s impossible to fully anodize an entire part. After all, the metal must be submerged, yet suspended in the bath, requiring a holder of some form. Any part of the metal concealed by the holder won’t be anodized, so it’s important to position your parts carefully and minimize obstructed areas as much as possible.

Everything You Need to Know About Vapor Polishing

Have you ever wondered how they make super-thin, transparent plastics, like those used for eye contacts? It’s called vapor polishing. This is a technique used to polish or finish a plastic product to achieve transparency. So how exactly does this work? Read on to learn more.

How Does Vapor Polishing Work?

Vapor polishing is a technique that smooths out plastic resin material at the microscopic level to get the desired effect. This is done using a Weldon 4 solvent that reacts with the surface chemistry of polycarbonates. This solvent is heated to boiling and the vapors are sprayed on the plastic. The plastic surface then melts and fills in the small holes and scratches. When the vapor is gone, the plastic once again becomes solid.

Does the Plastic Need to Be Sanded?

Yes. Since vapor polishing works at the molecular level, it can’t take out large deformities in the plastic. For that reason, Acrylic Art will sand your parts before we vapor polish to a surface between 1000 and 1500 grit. From here, the vapor polishing only takes a few seconds before the product is finished.

Can Anyone Perform Vapor Polishing?

No. Vapor polishing should only be performed by a trained professional as the process could be dangerous if you breathe in the vapors In fact, vapor polishing is done in a highly controlled environment where the worker wears a breathing respirator. There are also suited up workers stationed outside the working chamber to offer assistance if needed. For all these reasons, it is advised not to try this on your own.

Does Vapor Polishing Harm the Environment?

No. When vapor polishing is done safely, it is not bad for the environment. Our facility pulls the vapors through a three-stage carbon filter to avoid any contamination to the atmosphere.

How Long Does Vapor Polishing Take?

The lead time on vapor polishing is short. In fact, once the vapor is applied to the plastic, it only takes a few seconds for it to become clear. There is no need for repeated exposure to the surface area. This means a large piece of plastic can be vapor polished in just minutes. After the vapor is taken away, the item becomes hard and is ready for use.

Is Vapor Polishing Cost-Effective?

Yes, especially when compared to hand or machine polishing. Furthermore, it would be impossible to polish by hand those geometric shapes with recesses and pockets. With vapor polishing, however, you can reach the deepest grooves for an even polish. The result is then immediate.

Is Vapor Polishing Right for You?

At Acrylic Art, we are here to help you with any vapor polishing project. We also offer an array of other finishing services. Contact us today to achieve the desired finished project you want. Our friendly team can be reached at 510-654-0953.

And when it comes to manufacturing medical products, CNC machining is fast and inexpensive. Read on to discover all of the benefits of using CNC machining for making medical products.

No Fixed Tooling

Using a mold tool can take an additional 3-4 weeks compared to CNC machining. With a mold tool, you not only have to make the mold, but samples have to be approved and molding parameters have to be optimized. This just adds time and more costs to the process whether it’s a small or big production run. This includes single one-off parts, too. With CNC machining, there is less investment and fast turnaround.

No Volume Limits

Once a digital CAD file has been created, the cutting program gets generated fast. This coding program can be easily utilized to make both multiple parts or a single part. Just push the button. This ability gives an upper edge when making one-off custom parts or single parts. That’s why CNC machining is often used for things like prosthetics and specialized medical parts. Other processes require a minimum order volume, which makes some projects undoable.

Works With Many Materials

CNC machining can work with many different materials, including tools, rigid materials and end-use parts. Other materials that it can work with include engineering-grade plastics, aluminum stainless steel and titanium.

3 Benefits of Utilizing CNC Machining For Your Production Process

The modern factory was first invented, or at least credited, to the work of Richard Arkwright. Arkwright patented a water frame in 1769 before building the Cromford Mill, one of the first prototype manufacturing facilities as well as the first successful cotton-spinning factory on the planet.

Nearly 200 years after Arkwright would help to pioneer manufacturing warehouses, the world would be introduced to Computer Numerical Control Machining, otherwise known as CNC Machining.

Understanding CNC Machining

CNC Machining is a popular form of manufacturing relied upon for quick, accurate, and high-level material production. The process of CNC machining was brought to fruition by Richard Kegg in 1952 during a project in collaboration with MIT.  Kegg and his team at MIT would work in concert to develop the Cincinnati Milacron Hydrotel, the first of many prominent pieces of CNC Machining technology. Now, decades later, that same model is utilized by manufacturing facilities around the world

CNC Machining can be accomplished in several different ways. With that being said, there are three core types of CNC machining to be made aware of.

  1. CNC Milling – This form of machining was brought to life by Richard Kegg. CNC Milling is a process that involves mounting and mixing with rotational cutting tools. Materials are cut and removed by the rotating tools to craft many shapes at a rapid pace.
  2. CNC Turning – CNC turning is a manufacturing process that involves bars of material held in place by a chuck. This material is turned by the chuck in a rotation whereupon it is fed into the tool until the desired shape has been crafted.
  3. EDM   – Also known as Electrical Discharge Machining, EDM is a type of metal fabrication process that leans on electrical sparks to shape the targeted material. Typically, this involves voltage being released between two electrodes until an electric arc is produced.

3 Key Benefits to CNC Machining

If you are looking for a reason to add CNC machining processes to your manufacturing facility, you can take your pick. CNC machining took hold in the 50s and still exists to this day. There are a variety of reasons that warehouses are continuing to turn to professional CNC machining solutions, including the following three reasons.

  1. Highly Efficient – CNC Machining requires fewer steps in the production process, thus allowing for a quick turnaround on all production processing.
  2. Advanced Software – Put control into the hands of your computer. CNC machines use CAD software that provides a multitude of functions and options that other processes cannot match.
  3. Automated System – Fully automated systems mean that your operators don’t have to expose themselves to the job. Step back and watch over the machine from a safe distance as the process handles itself.

Working with CNC machining processes allows individuals to manipulate a variety of common and popular materials including aluminum, stainless steel, and brass among others.

6 Tips To Consider When Purchasing Injection Molds

Injection molds are meant to make manufacturing easier and increase productivity. Of course, that’s only when the right one for each project is purchased. The wrong fit or design can result not only months of lost work and delayed production, but damage to the equipment itself. With this in mind, here are 6 tips you should consider when purchasing injection molds:

1. Timing Depends on the Project

For some projects, a general injection mold will do, and you will not need to plan too far ahead during the design process. But for more creative projects that depend on precision, you will need to start planning the mold design early on in product development. If it is a complete custom design or a rarely-seen one, you will need to allow for more time for both design and approval.

2. Collaboration is Key

The most successful and creative projects are when the part designer, mold fabricator and injection molder are able to communicate efficiently and collaborate. After all, you don’t want to go ahead and approve a mold design only to find out that it cannot be made to specifications or that it won’t actually function as the injection molder needs it to. Though taking the time to communicate every step of the process may feel like it’s taking extra time, it can save you a lot of time (and money) later on.

3. Anticipate Issues

Even the best planning can sometimes end up in errors, but you don’t need to let it take you completely off guard. Plan (set aside extra time and funds) for potential re-cuts, for example. You may need the mold to be adjusted a few times before the plastic portions are brought into the exact range they need to be in. You may even need to resize the design in general at some point.

4. Prepare Your Production Floor Team

Even the most efficient production / shop floor teams will appreciate advance notice for when any new injection molds are going to arrive. They will need time to install the mold where it needs to go and make sure it is connected properly. They will need to check a number of things like lift straps, hot runner and coolant controllers, heater plugs and cables, water manifold ports, fittings, hoses, bolts, and more. This cannot properly be done at the last minute.

5. Standardize Designs that Work for You

Many people wind up needing the same injection mold later on. You can maximize both cost savings and efficiency by making the design standardized. Additionally, standardizing different features like clamp slots and connection locations on different machinery can also save you both time and money (especially if you need to relocate the injection mold later on).

6. Cost Savings May Not Always Be Worth It

Even more basic injection molds require a high degree of craftsmanship and precision. While you may be able to trim costs on many projects by going with cheaper options, it is crucial to really evaluate whether or not you can afford small errors or misalignments on your current one. Even small savings can end up costing you big time down the road if it means having to scrap a ton of used up material or tools and having to spend more on labor costs.
