Automotive Air Bag Testing Instruments

Automotive air bag testing is a efficient guarantee for more accurate, reactive and reliable performance of air bag. Air bag is one of the passive protection systems for automotives, which is directly linked to passenger safety.
According to traffic accident analysis, two thirds of car crush accidents are happening in front of cars; therefore, front air bag system is more broadly applied.
In order to have better performance, air bag design, development and manufacture are all very important. The contents are as follows:
1. Automotive Air Bag Permeation Testing
The material of automotive air bag is a laminated film of rubber and nylon. Air bag is filled with helium when working.
The rapid filling of air bag is of great importance. It is a must for the passenger to be stopped by the fast filled bag which can also exhaust promptly. Therefore, excellent and proper permeation performance of air bag is very important.
Labthink DM 2/330 Differential and Equal Pressure Method Gas Permeability Tester can test film and laminated materials including air bag laminated material. This tester can execute differential pressure and equal pressure in the same chamber. Three specimens can be tested simultaneously in 3 chambers. Poisonous, explosive and other gases can be tested as well. The temperature control range is 5C-95C, which is very convenient to test the permeability performance of airbag during storage and when triggered by heat.
2. Automotive Air Bag Smoothness and Open Easiness Tests
Good smoothness and open easiness of automotive air bag are vital to backup air bags and quick reaction when the passenger is in danger. The material of air bag is rubber coated nylon. In order to test air bag smoothness and open easiness, Labthink Instruments Co. Ltd introduces airbag testers as follows:
A. MXD Series of Coefficient of Friction Tester is applicable in static and kinetic coefficient of friction test to plastic film, foils, sheets and paper. Through testing the smoothness of the materials, airbag safety can be guaranteed to meet the demands. This series of products includes MXD-01, MXD-01A and MXD-02.
B. FTP-F1 Friction/Peel Tester: is computer control, and can test the material coefficient of friction between room temperature and 99.9 Centigrade as well as peeling strength of laminated films and adhesive products, which is very important to air bag testing.
3. Automotive Air Bag Tensile Testing and Impact Testing
Automotive air bag receives the signal from the sensor, and turns open within a few seconds so as to protect passenger. Since the open speed to its full is in a limited time of 0.3 seconds so as to resist shock and attack from the outside. Therefore, it is a must for air bag with good tensile performance.
In order to guarantee excellent tensile performance, Labthink Instruments Co. Ltd. introduces new series of tensile and impact testers according to international regulations and standards.
A. Labthink PARAM XLW Series Auto Tensile Testers can test tensile, deformation, tearing, pierce, peeling and other items for films, laminated films and flexible packaging materials, etc. Put the air bag specimen onto the clamps, set the testing speed and start testing.
B. Automotive Air Bag Impact Resistance Testing
At the very moment of air bag opening, it will make a space to release the forward strength of the passenger. Air bag impact performance control can prevent air bag breakage due to low flexibility so as to effectively avoid protection failure of low air bag quality. Usually, impact is tested with falling dart impact tester.
Labthink introduces new BMC-B1 Falling Dart Impact Tester to test air bag impact resistance by falling dart method. It is to test the relevant strength needed to tear the air bag material according to ASTM D 1709, JIS K 7124 and GB 9639, etc. The whole testing process is automatic; testing data are processed by minicomputer.
4. Automotive Air Bag Seal and Leak Testing Instruments
Automotive air bag should be filled instantly by the burning helium when the sensor got the emergency signal. Therefore, automotive air bag integrated seal and leak testing is an important index for automotive air bag quality. Labthink Instruments Co., Ltd. introduces PARAM Leak Tester to test air bag seal and leak performance.
Labthink PARAM MFY-01 Leak Tester determines whether the air bag meets the requirements through observation of emerged air bag in distilled water with inside-out pressure difference. This tester is of simple operation and micro-computer control. It complies with ASTM D3078 and GB/T 15171 and provides accurate data.
5. Automotive Air Bag Peeling Testing Instruments
Automotive air bag is made up of the outer nylon material and the inner rubber. Owing to the long-term storage for emergency, a long period of aging, good peeling resistance strength of the nylon and rubber layers is very important so as to avoid insufficient gas filling caused by rubber layer peeling.
Labthink Instruments Co. Ltd. introduces PARAM XLW series of auto tensile testers so as to meet the testing demand for air bag peeling. This tester is applicable to test tensile, peeling, deformation, tearing and adhesive strength of laminated films and adhesive tapes. PARAM XLW Series Auto Tensile Testers are mini-computer control, and can test multiple data with reliable and accurate results. These testers are equipped with professional software. Also, they are complying with ASTM, ISO, JIS and GB standards.

Oil Change - Extending the Life of the Engine

Every driver has seen a vehicle cruise down the road spewing blackish
exhaust and sharing an occasional backfire: that engine is whipped and
an environmental hazard to all! If proper maintenance had been
administered to that poor vehicle, an oil change done every 3-5,000
miles, the engine life of that car could have been prolonged for years
to come, possibly destined to become a “classic” in someone’s garage.

Under perfect circumstances a car or truck can go 6-7,500 miles between
oil changes, but very few drivers maintain and operate their vehicles
under “optimal circumstances”. The standard automobile is in need of an
oil change every 3-6 months or every 3-5,000 miles at the longest
without the risk of damage occurring to the bearing, journal or cylinder
wall surfaces of the engine. Most owners view fluid maintenance for
their vehicles as an afterthought, something that can be put off until a
time that is convenient to take the car in for service. The reality is
the oil filter’s job is to remove contaminates: dirt, carbon, metal
particles, and other foreign matter from the oil before damage is done
to the engine, so regular oil and filter replacement is of vital
importance.

The cost of an oil service check can range from $20-$50 (on average)
depending on the year, make and model of the vehicle; a high end foreign
make may be on the higher end, and a flex fuel or electric car may
require a special filter which may push the cost up, as well. In years
past, gas fueled cars could go as long as 6-7,500 miles between oil
changes before the risk of engine damage became a concern to the driver.
Diesel and turbo charged cars and trucks were the type that required an
oil change around 3,000 miles, due to their particular engine needs.
But today’s cars are designed to be lighter and more fuel efficient,
which comes with the new 'full-flow filtration' system: the oil pump
sends all the oil through the filter before it enters the crankshaft
bearing, cam bearing and valve train, ensuring only filtered oil enters
the engine. These filters are smaller and lighter, and the need to
perform an oil change on schedule is absolutely necessary. Newer cars
and trucks have a light that comes on (and remains on) when service is
needed. The service should include the oil, a new oil filter,
lubrication of chassis components and some businesses will also check:
transmission fluid, power steering fluid, windshield washer fluid,
antifreeze and/or coolant, tire pressure, air filter, Serpentine Belt,
wiper blades and the vehicles lights.

An oil change is more than just maintaining the vehicle’s performance
and amount of fuel consumed per mile, it is an insurance policy on the
longevity of the engine life of the car or truck. If the fluids and
lubricants are neglected, the engine can suffer damage, performance
declines and eventually the engine will seize up, and the entire engine
will need to be replaced or repaired; either way an enormous expense the
driver could have avoided with proper maintenance.

Options in Oil Change Services

Your car requires regular oil changes throughout its lifetime. There are a couple of ways to accomplish this task. You can either take care of it yourself or have a mechanic do it. When you choose a mechanic, you can either trust in your local auto shop or go with a national brand that takes care of oil changes specifically.Learning how to perform an oil change yourself is actually quite easy. All you need is the proper tools and understand how your car needs to be handled. When it comes down to it, there are only 3 major steps in the process: drain the oil, replace the filter, replace the oil. Seems pretty simple, right? By performing this maintenance task yourself, you’ll save about 50% to 60% off the retail cost of an oil change.When you take your car to a local mechanic, they are more than qualified to take care of this simple task. They are also someone who can briefly review what’s under the hood and give you a quick assessment of the health of your engine. Think of it like going to the doctor to get a vaccination. It’s a quick appointment, but the doctor is there to check up on you briefly too. This is especially helpful if your auto mechanic has a history of repairs and inspections of your car. They can know what it looked like the last time you came in, and give you a quick review of your car’s performance.There are, however, more convenient and more inexpensive options out there. When you take it to a major brand, these companies are able to buy oil and filters in incredible volumes, passing the savings on to their customers. Some are full service auto mechanic shops, others are on the good oil change facilities where you can get your oil changed so fast you don’t even have to leave your car. Going with one of these companies certainly takes the hassle out of getting an oil change for people with busy lives, people who would have otherwise probably hesitated to get it done and risk damaging their car’s engine. Regardless of how you choose to get it done, it’s an important task to maintain your car. It’s the compliment to every working part in your engine and without it, your engine would seize up and your car would be worthless. It’s not necessary to choose one of these methods and stick with it either. Whatever works for you at the time is best, as long as it’s getting done at the appropriate times.

How Often Should Oil Change Be Done?

In the olden days, the rule of thumb for oil change frequency was every
3,000 miles. The 3,000 mile was drilled into the head of every vehicle
owner, mechanic and driver on the road. Over the years, this has
changed. Now this car maintenance task frequency varies depending on the
brand, model, driving habits and year of the car. The requirements for
each vehicle will be notated in that particular automobile’s owners’
manual. Here are some things to think about regarding this crucial
preventative maintenance task:

- What is the recommendation for oil changes? It will depend on the
vehicle but may be 5,000, 7,000 or even 10,000 miles for that particular
model, brand and year. To be sure, even mechanics check the
manufacturer’s recommendations because the rules have changed so
drastically.

- Why have the recommendations changed so dramatically? There are
several reasons. For one thing, automotive engineers redesigned the
systems to work more efficiently which allows them to burn and dirty
less of the lubricant. For another, mechanics learned that it wasn’t
actually necessary to change the lubricants out so often, after all.

- What can happen to a car with dirty or low lubricants? Most motorists
know that having pure and ample oil is crucial to a properly functioning
engine. There are many metal parts that create friction when they rub
together. If there isn’t enough lube between them, they can damage each
other, jam up and basically kill the machinery. Dirty oil can also clog
up the works as debris and sediment cause everything to come to a
grinding halt. Not performing this car care task will mean that your
vehicle won’t live up to its potential.

- What are the benefits of fewer oil changes? It’s beneficial to the car
owner because he or she won’t have to pay for as many servicing
appointments. It’s beneficial to the environment because the earth
doesn’t have so much of this dwindling natural resource used up.

- So, this is a 'green' thing to do? Yes. It's environmentally friendly
because it uses less fossil fuel in the changing and less gasoline
getting to and from appointments.

- What about synthetic products? There are synthetic lubricants on the
market today which many mechanics recommend. They are said to evaporate
less, promote engine longevity and leave less of a carbon footprint.
Whether they’re right for your auto should be discussed with your
mechanic.

- What kind of driving conditions would require more frequent changes?
If the weather is extremely hot, cold, or humid, if the car is driven in
mountainous regions, if trailers have been towed, if lots of
stop-and-go traffic has been experienced or if lots of short repeated
trips have been taken.

The old-fashioned 3,000 mile rule has changed. Nowadays, motorists
should check their manufacturer’s recommendation which is found in the
owners’ manual. Every car is different and the oil change frequency will
vary depending on the brand, model and year of the car as well as the
region and manner in which it has been driven.

Which Mazda is Right For You?

When was the last time you went car shopping and knew before you went to
the dealership what kind of car you wanted to buy? For most of us, the
answer is never. For some, just the mere thought of having to purchase a
car brings on anxiety because you have no idea where to begin to figure
out what it is that you are looking for in your next car, even if you
know which brand you want. Fret no more, through the use of technology
and visits to your local Mazda brand dealership, you can figure out what
model car is right for you. It is the intention of this article to
discuss how to determine which model is right for you in an effort to
aid you in your search.

The first and perhaps most obvious way to determine which model Mazda is
right for you is to utilize the model selector on the corporate brand
website. This tool allows you to select items that are reflective of
your needs and desires, such as price point (i.e. MSRP), seating
capacity, fuel economy, and horsepower, as well as your vehicle type
such as a car, sports car or crossover/SUV/multi activity by reviewing
information about each product. In addition, you can also filter out
available features such as a 4 cylinder engine, power moon roof,
navigation system and rear seat entertainment system, to name a few.
While this tool is designed to help prospective buyers with determining
which model is best for based on prepackaging, it is more controlled in
the sense that you are merely selecting from what is already available,
as opposed to your next option. Another way to determine which model
Mazda is right for you is to utilize yet another tool on the corporate
brand website: build a vehicle. Although this tool is similar to the
model selector to the extent that you control the vehicle
specifications, the difference lies in the fact that you get to
literally design or create your own version of your preferred vehicle
type. As cool as this may sound, and it really is, the more you know
about your needs and desires, the more enabled you will be in making
decisions in the creation process. Specifically, you will to select your
model (i.e. car), trim (i.e. manual or automatic transmission),
exterior color and vehicle options. The third way to determine which
model Mazda is right for you is to go to your local dealership and test
drive various models. As great as technology can be, there is nothing
like the thrill of test driving your dream car. Obvious perks of doing
so include the ability to make adjustments in your needs and desires,
based on your driving experiences.

Whether you are car shopping for the first time or the fifth time, if
you don’t know what you want it can be a grueling and time consuming
process. Luckily there are several ways available to help you in
determining which Mazda model is right for you. Specifically, you can
utilize the model selector and build a vehicle, both on the corporate
brand website, as well as test drives at your local dealership.
