How to Select a Moisture Analyzer for Moisture Plastic Analyzer

Published

moisture analyzer

When you select a moisture analyzer for a moisture plastic analyzer you will need a model that not only can quickly but also accurately gauge the moisture content of these resins.   And as with many quality control requirements that involve moisture content, you’ll want a moisture balance that can meet standards set by trade associations and professional organizations.

In this post you’ll get a briefing on the following:

  • why low moisture content is important in plastic resins
  • a technical standard that applies to determine moisture in plastics
  • how benchtop moisture analyzers work
  • a standards-compliant moisture analyzer
    for plastic resins

Why Low Moisture Content is  Important

Owners of injection molding companies and operators of injection molding machines are aware that incorrect moisture content in plastic resins can result in an inferior finished product.

Product shipped from resin suppliers may have the specified moisture content but ambient conditions at the injection molding facility could raise or lower moisture content before it is placed in the injection molding machine hoppers.

Companies involved in producing quality products by injection molding take steps to ensure proper resin storage. This along with using commercial drying ovens are two important steps in quality control.

Periodic checks with a benchtop moisture analyzer for plastic resins provides assurances that moisture content is on target, or otherwise call for pre-processing adjustments.

A Standard for Determining Moisture in Plastics

The American Society for Testing and Materials (ASTM) has published standard governing testing the moisture content of plastics*. It employs what is called the LOD method, or the loss of weight on drying. This is also described as the thermogravimetric method.

Taken directly from the published standard the test method is summarized here:

“The specimen is spread onto a sample pan that is supported on a balance in a heating chamber that has been preheated and equilibrated to the specified idle temperature. It is then heated to vaporize the moisture. The analysis is completed when the indicated weight loss falls below a rate specified in the test conditions. The total loss of weight is integrated and displayed as the percent of moisture. Both the analyzer’s balance and heater are calibrated to NIST** standards to achieve precise and accurate results.”

How a Benchtop Moisture Analyzer Works

The ASTM standard briefly describes the process.  Here is a bit more detail.

A benchtop moisture balance employs a drying process to extract and measure moisture.  It combines a precision balance and a heater.  In a simple 4-step procedure:

  1. The drying process parameters are entered on a keypad. These are the drying temperature which may include how the heat is applied (a.k.a. heating profile) and shut-off criteria.
  2. The sample is placed on a weighing pan located in the drying chamber.
  3. The drying chamber is closed and the analysis begins.
  4. The instrument calculates the moisture content by comparing the initial weight of the sample to the weight after drying is complete.

As in the standard, the total loss of weight is integrated and displayed as the percent of moisture.

Halogen quartz glass is generally the source of drying heat. These heaters provide constant even drying of the sample after temperatures are programmed in by the moisture analyzer operator. Temperature is generally maintained within 1⁰C of the selected setting.

While most analyses involve ramping the temperature to a maximum of 160⁰C or less, in special cases higher temperatures may be necessary to achieve complete drying. The analysis automatically terminates either when the dry weight is stable or at a time specified by the operator.

For more detail on how these instruments work please check our post on moisture analyzer questions and answers.

A Moisture Analyzer for Low-Moisture Plastics

A moisture balance complying with ASTM D 6980 – 04 is the  DSC 71P available from Tovatech.  This model provides precise moisture analysis and is equipped with a default program to test 75% of the most commonly used resins.  The  DSC 71P is highly recommended for:

  • Molders processing a limited number of plastic formulations
  • Molder having QC problems related to moisture content
  • Molders who need to replace an old moisture analyzer
  • Molders adding a new production facility and need another moisture analyzer to support it

It is also an ideal tool to check the moisture content of incoming resins, confirm moisture content before filling hoppers and check the performance of bulk dryers.

The  DSC 71P Moisture Analyzer Close-up

Thermogravimetric moisture analyzers such as the DSC 71P calculate moisture content by loss of weight on drying (LOD). This is more environmentally friendly and far less complex than the Karl Fischer moisture analysis requiring a high degree of skill and the use of hazardous chemicals.

Yet due to the very small amounts of moisture that can be tolerated in resins such as the <0.02% for polyethylene terephthalate sensitivity is critical. To address this the  DSC 71P has a readout of 0.0001g or 0.001% moisture. The repeatability (standard deviation) is ± 0.01% moisture content for a 10g sample.

Other features include:

  • 3 free tech support phone calls for optimizing test procedures
  • Custom programming for your resins available prior to shipment
  • Short measuring time. Get results quickly with fast and uniform heating
  • High repeatability. Superior accuracy even when weighing small samples
  • Real-time graphic display. Watch drying take place via a connected PC screen
  • Accuracy checks using sodium tartrate dihydrate with its stable moisture content

Simple Resin Moisture Calculation

Once programmed with up to 20 testing procedures all the operator has to do is call up the program for the particular plastic to be analyzed. The unit’s vacuum fluorescent display shows the drying profile (standard, quick, step, or ramp), time, and temperature (30⁰ to 200⁰C in 1⁰ increments) as well as shut-off criteria.

The unit comes with a 9mm (3.5 inches)  sample pan, WinCT Moisture software, 30 g sodium tartrate dihydrate for accuracy checks,  tweezers, a spoon, a RS 232C cable connection, and the instruction manual. A dot-matrix compact printer is available as an option for record-keeping. Other options include a 50 g calibration weight and a certified temperature calibrator.

A Resin Moisture Analyzer at an Attractive Price

Plastic resin moisture analyzers equipped with large libraries can cost around $10,000 or more depending on features. This is a substantial investment for small to medium-sized injection molding companies. The DSC 71P moisture balance with its broad range of features and outstanding accuracy is available for under $5,000.

Caution should be exercised when looking at lower-cost units because of their inability to deliver the high accuracy and precision needed for quality control when working with low-moisture resins.

Contact the scientists at Tovatech for advice on selecting and using a moisture analyzer to support your injection molding operations.

How an iOS App Will Give You Your Desired Customer Base?

How an iOS App Will Give You Your Desired Customer Base?

Smartphones are common and it is a rare occurrence that you will find someone without one. Moreover, Android and iOS are the only two key players when it comes to the mobile operating system as they control 99+ market share.

But among them, if we’re to compare then Google’s Android would take a lead with its 73% acquisition of user base out of the total smartphone users present in the market according to consensus 2021.

Then why are we suggesting you go for an ‘iOS App’ for your business instead of an android one? Well! There are reasons and not one, but we have a total of four of them.

Builds Brand Reputation

Brands work all their life towards building a brand reputation and they cannot manage to hamper that at any cost. With everything that they do, whether it be a big campaign or a social media post, they try to embed their brand inside everything.

Having an app developed for your business will provide a strong brand recall, recognition, and reputation system. Every time a notification pops up, or they get to see your app logo, which is usually your brand logo, they get to think about your organization, and such kind of free marketing should be bootstrapped at the earliest.

Customer With Better Purchasing Power

While targeting the audience should be your priority, many tend to ignore it, and then it hurts your business overall. But do you know that even with a 27% acquisition of user base in the smartphone market, iOS users would be a much better audience?

They have comparatively more purchasing power. Duh! They already have one of the most expensive phones on the market. So, they would end up subscribing to your services or purchasing the product that you sell.

Such a user base means that you’re sitting on a pot of gold and all you have to do is make sure your service/product is of some use and that it reaches your potential audience.

Better Security Than The Android Platform

The iOS platform is much more secure than Android and with that, we can say that it automatically makes sense that an iOS app will be much more secure than an Android one, wouldn’t it?

If you don’t believe that then you can refer to the San Bernardino terrorist case where Apple refused to decrypt iPhones acquired by the FBI from a group of terrorists. They claimed that with the iPhone they sell privacy and they cannot break their oath for whatever reason it might be.

So do you agree now that having an iOS app would be much better for your business? Well! You should, but one question still stands: ‘How To Get an iOS App Developed’?

Well! You would need to go and search for IOS App Development Company that can fix one up for you. But why go looking for one, when you can refer to the industry leader with about 11+ years of experience in the industry.

We are talking about ‘TechAhead’, a company that has been continuously bagging awards after awards and being the best Android App Development Company continuously.

What is their USP? Well! Not to say much, but they have been the trusted choice of Audi, AXA, ESPN, ICC, and much more high-profile clients. Now, what does that tell you about TechAhead?

Yes! They are the most trusted and preferred among the best, which is what you need for your business too because we believe that you’re someone who wants the best of the best only.

Virtual Receptionist Guide: Start To End Game

In the course of your work, how frequently did your phone ring? As a consequence of not being able to pick up the phone, how many new positions have you lost during the current month? Have you forgotten to get in touch with them? Your probability of losing a couple is high. There are probably a lot of them.

Perhaps a reliable virtual receptionist for your business is an arrangement you are looking for. It is possible for them to handle that load of calls for you and to deliver exceptional client support. A seaward call reply mail is definitely not this.

Why does it need to be so complicated? How is this going to work? To help you make sense of virtual receptionist facilities for your business, we have gathered all the data you need to know here.

Is A Virtual Receptionist Service Right For Your Business?

Reevaluating conventional receptionist occupations for actual client support professionals is a virtual receptionist service. The virtual receptionists for your business are contacted by phone calls at your business number (or versatile). An accomplished client support expert at that point replies to those inquiries. You determine how they respond to a call based on the type of business you have and the type of cooperation you need from your customers.

Involvement in significant exchanges is a profound part of the work of virtual receptionists for your business. The answer to questions is unhesitating and exact owing to the information they possess.

A reliable virtual receptionist for your business provides you with the flexibility to use the facilities as much or as little as you require, which is a key distinction between a conventional secretary and a reliable virtual receptionist for your business.  

  • Full-time availability during business hours
  • During times when you are inaccessible or unable to contact you in a nonchalant manner
  • Break over the Easter holiday or Christmas
  • An absence of a current employee or their inaccessibility

Also, you can choose if the virtual secretary for your business handles only messages or everything related to reservations. Additionally, the system can be customized to meet the evolving needs of your business. To improve the business cycles and consolidate data for the receptionists, the facility is continually evaluated.

In Conclusion

To have it up and to run, you need to take action or present data to the virtual receptionist for your business to have it up and to run. Follow these steps to complete the process:

Your mobile phone and landline should be configured for call redirection. You can ask for directions if you do not know how to do this.

Access all the products you use to manage your occupations, including email, schedules, installment stages, and the administration framework. More importantly, we can provide guidelines on how this can be achieved.

Provide any business security you may need to oversee client requests and appointments, including client group record access, the value of the facility, and value records.
