What does the High Heat do in Spring and Electronics Enclosure?

In line with the spring decided to give us a small sneak peak on what mother earth has in store for us, I have decided to write about the plastic material description and what types of these materials should be used on higher heat materials. Especially with the high heat weather, it is important for us to be knowledgeable on this aspect.

The ABS material has set a melting point of 176 degrees Fahrenheit. If a design engineer is planning on a project that has the potential to have an above temperature than 176 degrees Fahrenheit, you will have to take a look on a very heat resistant material. We should start with Noryl®.

This material is a modified Polyphenylene Oxide which constitutes a very good high and low temperature performance that has a wide range of temperature from -40 degrees F to 203 degrees Fahrenheit. Not only that this material will be able to withstand the super high temperature but it also have a very high impact. It also has a very good mechanical strength, and it can only mean that the products that are being molded using this material can resist and be able to maintain the integrity of some potential accidents. Such as low drops or other forms of abuse.

Also, in addition to this, this material has a very excellent stability under very heavy load. It can also protect the equipment from a possible collapse that can happen under weight and pressure. One of the major downfalls of this material is that it can be weakened just by using a petroleum. Therefore, once a petroleum-based products touched this material, it can lose its integrity. It should not come near close to a Noryl® fixture. Products like these suh as coolants or some cutting oils should be petroleum free.

Regardless of this, the Noryl® is a very efficient and easy to work with material. Because it can give a whole wide variety of different fabricating options that also includes the thermoforming, ultrasonic sealing, and bonding. Also including is the CNC machining of this specific material can result to a very clean and smooth cuts to be able to increase the professional appearance of the finished product. Because of the heightened material cost, several plastic molders can apply a additional surcharge for using this material and companies can require minimum quantity orders.

All about IP Protection Rating: What Rating can I Use?

Just recently, a very close friend of mine decided that she wants to sell some of her stuff. These are the things in her house she thinks she does not need anymore. One of the items she owned was a custom-tailored dress that she had made for a very special occasion. For me it was a very beautiful night gown with a very unique and pretty sense of style. For me, my friend is a fashion icon of her own right.

She utilized elements and colors that she saw from different gown styles that can fit her body type and her taste in fashion. She had them all mashed up into one. Since it is a custom dress that had to be taken and repaired for a few times, she is now having a hard time on deciding how she can advertise the dress? She is not sure what style her dress shows now because of different ideas rolled into one. With this, I suggested that she states in her advertisement when was the last time dress was won and for what occasion it was used.

There are also other things in life we find it hard to put the right title on it. There are items that are hard to designate a title with. While there are things that are created with a specific purpose and intention in mind, it does not mean that they have formal certifications. This also holds true when it comes to the electronics enclosure.

There are enclosure series produced by companies that are coming from specific characteristics the designers had in mind. They wanted and desired to have an enclosure that can meet the IP66 standards. This means that their electronics enclosure should be able to protect the equipment from the water and dust ingress that can protect and shield the electronics effectively inside the enclosure.

Little did they know that the IP ratings of enclosures can be greatly affected by the way the enclosures were machined. While it makes a lot of sense the the whole idea behind the IP66 is that the water should be prevented from entering and getting inside the electronics. While machining a hole for customization purposes can potentially allow the water inside the enclosure and it can bring great harm to the equipment housed inside. This can create a new opening and there are potential ways to circumvent and damage the rating.

This is the main reason why some of the enclosure manufacturing companies cannot certify their enclosure design because they will go against the standard IP rating definitions because some of the characteristics will be totally compromised. Because they know that the need to machine the equipment is depending on the need for accommodating certain connectors and cables for the equipment. At this point, the rating is no longer valid.

There are cable glands available to prevent the water from entering the enclosure. Just ask the company you are sending your inquiry to if they have one of these available. It can help your equipment be protected from possible water ingress.

Obvious Similarities of an Enclosure and a Flamenco

Obvious Similarities of an Enclosure and a Flamenco

The dance lessons continue and I’m learning more than I thought I would. Really, I always assumed it was one or two moves and then just add in some flair, like dips or a fancy foot move. But no, there are STEPS to these dances. And one must know them in a specific order, from start to finish, so that as part of a couple, he or she can lead or be led. Blows my mind really. So are there other processes in life that we must follow exact steps in order to correctly complete the process? Why, I’m glad you asked. Yes, yes there are.

It is surprising to know that are obvious similarities of Flamenco to an enclosure. Actually almost all form of dances is similar to the process of building an enclosure. Dancing is not akin to just forming the steps and just adding extra poses to make it brilliant. The dancer should know how to give the steps and dance gracefully by order. There is no brilliant thing that is done overnight. There are crucial steps that are needed to take in order to lead the dance and be able to finish it gracefully. This is just really amazing when you think that in also in life, you need to take slow processes for you to master the exact steps and be ready to make and complete what it is needed to be done.

With this in mind, I would like to help you understand this by illustrating how a plastic enclosure’s lid is secured by following these steps. For your reference, here are the steps below:

1. First, arrange the screws on the cover and seal them by threading them through the cover holes. There are different holes for different types of screws. For the enclosure cover, it accommodates WA, WC, & WP series. These are considered to be captive screws that is primarily made for stainless stell.

2. After the first step is done, this is the time to have the cover placed over the base or the bottom half of the enclosure. Then arrange the screws or align on the cover over the corresponding holes on the base.

3. Have the screws loosely assembled in the cover in sequence until the screws are already finger tight.

4. Have the screws tighten up to a torque of 8-inch pounds. To achieve a better accuracy, use a torque screw.

5. To make sure that the sealed joint is tight enough and the gasket covered is properly aligned, inspect everything. It should be aligned with the lip in the body. For the 4-hole covers, the engineer should have the middle of the cover be squeezed tight against the base of the enclosure. There are times that when doing this on a larger enclosure you will hear a snap noise. Do not worry because this is a normal scenario and it just indicates that the sealing lip in the base is now properly seated and aligned with the cover gasket.
