Toy Safety Testing

With the steady growth of the world economy, consumer demands of toy products are increasing rapidly. Based on the original intention of health and safety, countries or regions around the world have established strict standards for toy control, and constantly updated and refined. Toy safety problems are constantly happening and the relevant laws and regulations of the sanctions are increasingly severe,which bring great challenges to toy manufacturers, importers and retailers.In order to ensure the safety of toys, different areas have different safety standards,in which European standards is considered as a wider range of applications, it needs to pass the strict EN standard testing,no exception for toys. Several of the most commonly used toy safety test are: torque test, drop test, impact test, Compression Test.

(First Part)

Torque Test: Torque test steps: apply clockwise torque force on the component in 5 seconds , twist to 180 ° or 0.34Nm, hold for 10 seconds and then return the parts to the relaxed state, counterclockwise repeat above process. Less than or equal to 6 mm, a force of 50 N + 2N is applied, and if the size of the maximum protruding part is larger than 6 mm, a force of 90 N + 2N is applied.Put on pounds in 5 seconds and keep for 10 seconds.

toy torque test

Judgment criteria: toys designed for small children who can’t sit up alone should not be cracked,if the crack does not cause damage obviously,it is acceptable.Toys designed for children under 3 years should not produce small parts, contactable sharp point and sharp edge. Masks and helmets should not have exposed cusps, edges, or loose materials that can enter the eye. Oral toys and toys used in the water should not produce small parts.

Equipment: Large Torque Fixture, Middle Torque Fixture, Small Torque Fixture, Torque Gauge

Standards: ISO 8124-1, GB 6675-2, EN71-1, ASTM F963, 16CFR 1500

The structure and the advantage of the new style drum track

The traditional drum track is with solid structure. It is very heavy, weighting about 250kgs. And it will be bigger when the concrete mixer drum capacity is larger. Because the track with solid structure is lack of the deformability, the welded track onto the drum often snaps when using for some time. If only reducing the sectional dimension of the track ring to reduce its weight, the rigidity of the track will be decreased a lot that it cannot bear the weight of the drum. So it is a big challenge for the engineer to reduce the weight of the drum track.

The new style track of TOPIVOT is with hollow structure. It can reduce the weight and the production cost of the track.

The hollow drum track ring is produced by entirely ring rolling. In the meanwhile, increasing the forging pressure, then by the process of repeatedly heating-blank making-post forming, so it can ensure the compactness of the structural constituent after forging. We use the special mold to make the hollow part by roll forging. Because the track is formed by repeatedly heating, the quality is much better than the traditional one.

When design the hollow structure track, the actual using conditions should be considered. When the mixer drum is full loaded, the center of gravity will move forward to the drum head. So the small side thickness of the track should be 3 to 5 mm more than the big side thickness to ensure the support stiffness for the full loading condition. And the height of the outside of the track is the same as before, so it will not influence the integral rigidity of the track.

Comparing with the traditional track, the hollow track ring has the following advantages:

1.     The weight of the track can be reduced by 20%, about 30 or 40kgs. The cost can be reduced about by 15%.

2.     Hollow structure can absorb some welding stress when the track is welded with the mixer barrel.

3.     When welding the track with the mixer drum, because the contact surface is reduced, the positioning is easier.

4.     Because of the hollow structure, if the track needs to be replaced, the drum track can be disassembled only by using the gas cutting and blowing the welding in the drum’s axial direction. But the traditional solid structure track doesn’t have the space for blowing and it’s difficult to be disassembled.

5.     The hollow part of the drum track doesn’t have to be finish machining. It means that the finish machining surface of the drum track is reduced so as to reduce the machining time and increase the production efficiency.

Introduction to Polarity Methods for MTP/MPO Systems

It is important to ensure that the optical transmitter at one end is connected to the optical receiver at the other in any installation. This matching of the transmit signal to the receiving equipment at both ends of the fiber optic link is referred to as polarity. For traditional cabling systems using single fiber connectors, such as SC or LC, Keeping the polarity simple is to ensure that one connector has one side, one pair of matching B side, and the other connector on any incoming line or permanent link. But for the high-density MTP/MPO array connectivity systems, it has their own requirements for maintaining proper polarity. Now Sinda will illustrate the methods for maintaining polarity in pre-terminated MTP systems.

MTP/MPO Array Connector Structure

Array connectors terminate multiple fibers in a single high-density interface. There are 4, 6, 8, and 12-fiber array connectors. And the most common are 12-fiber array connectors. As shown in the following picture, array connectors are pin and socket connectors, there are a male side and a female side. As well as, each MTP connector has a key on one side of the connector body. When the key sits on top, this is referred to as the key up position. In this orientation, each of fiber holes in the connector is numbered in sequence from left to right. We will refer to these connector holes as positions, or P1, P2, etc. In addition, each connector adds a white dot to the connector body so that the connector’s location 1 is specified when the connector is inserted.


Three Polarity Methods for MTP/MPO Systems

Three different ways for maintaining polarity in pre-terminated MTP systems are defined in TIA/EIA-568-B.1-7. These three ways define installation and polarity management practices and provide guidance in the deployment of these types of fiber array links. Once you choose one way, These practices must be in place to ensure that the correct signals are delivered throughout the installation.

Method A

Method A employs “key up to key down” adapters to connect the array connectors. As shown below, this method maintains registration of Fiber 1 throughout the optical circuit. The optical fiber 1 in the proximal box matches the optical fiber 1 in the relay component that is matched with the fiber 1 in the relay box. Optical fiber circuits are accomplished by using a flipped jumper at the beginning or end of the permanent link to ensure that the transceiver is in the right direction.


Method A provides the simplest deployment and works for single-mode and multimode channels, as well as can easily support network extensions.

Method B

Method B uses “key up to key up” adapter. An optical fiber circuit is accomplished by using a direct patch at the beginning and end of the link, and all array connectors match the key up key”. MThis type of array mating results in an inversion, meaning that Fiber 1 is mated with Fiber 12, Fiber 2 is mated with Fiber 11, etc., to ensure that the appropriate configuration of transceiver operation, a box must be inserted into the internal fiber optical fiber link with 1 at the end of 12.


Method C

Method C uses “key up to key down” adapters. The fiber circuit is completed by utilizing straight patch cords at the beginning and end of the link, and the same cassettes as in Method A. The difference between this method and Method A is that the flip does not happen in the end patch cords but in the array cable itself.


Sinda can offer MTP/MPO Connectors and patch cord at best price with high quality. If you have any question please do not hesitate to contact us, it will be our pleasure to sever you.

The Puzzles Of Small Profits

  1. There is a risk of small profits

Some customers, he will tell you directly to him 20% discount after you sending price sheet. But you know that China’s manufacturing industry is really very rare to do this profit, in fact, it is very low I know some of the industry, such as making fans, their profits are really very thin, even thin to the exchange rate where there is little fluctuation, for them are fatal.

I know that there is a very large factory suddenly drained, he told me that his price is lower than his peers This is the fan industry in terms of the industry can not imagine, because it is entirely a loss of business: the market bigger, every customer is the next, and then to the loan, to finance. But one day suddenly a link is a problem; the whole building may collapse on an instant.

  1. High prices will always defeat the low price

I found a lot of small factories that do not have the ability to take orders independently, and they tend to choose low-cost tapping this way to minimize profits. But in fact is always a high price to defeat the low price, cheap can not beat the high price. Because you do not have enough profit, some customers do not pursue a high status, but I must have. Because when you do their own profits are gone, then you do not have more in-depth development or sustainable development of space.

  1. You said it was a dark horse, I said it was professional

Many of our suppliers, including peers will feel very strange, that from where to kill such a dark horse, never said before, why a short span of two or three years suddenly rushed out. In fact, we have been in this industry for a long time, almost a decade.

In fact, for us, roller shutter motor we have been doing, all the way to do down, so cooked can not be cooked again. Although we did not do this factory before, but because we are familiar with this product, familiar with the market, know which market has some big customers, know what kind of market to get, what degree of market acceptance, the price can be sold to the number and many more.

  1. Anti-risk: a profit, two to the market

For us, we will choose a more conservative way. First of all, I have to ask each order to be profitable; secondly, to make the whole market more extensive.

On the one hand is to control this risk, on the one hand is to try to make your market bigger, wide, so you can avoid it by a particular market impact too much.

  1. In the industry to make word of mouth, you succeeded

In fact, when you do in rolling door motor industry for a long time, especially as we are a relatively small circle, sometimes do not need you to tell the customer what, he asked you have done with whom, and even he does not need you to send the door motor samples. In fact, our products are definitely to send samples, not you can look at it, he wants to test performance, to see if you have no certification, of course, we will do all of these certification in front. That is to say, the product to a certain extent, in fact, is a kind of your reputation.

Why Is Stormwater Management Important? Why Should It Be Incentivized?

During a heavy rainfall, impervious surfaces such as parking lots, rooftops, and roads do not allow rainwater to be absorbed into the soil, resulting in large amounts of water traveling directly into our waterways. Stormwater runoff quickly becomes contaminated with pollutants, oil, garbage, and debris which is transported directly to our watersheds. In the District of Columbia, 43% of the land is made up of impervious surfaces which creates huge surges of water during heavy storms that not only contaminate local water sources but can also cause the erosion of stream banks over time.


In order to prevent this massive surge of polluted water from entering our streams and rivers,GS Rainwater Harvesting Tank strive to increase the amount of permeable land that can absorb rainwater or to harvest and store the water before it becomes runoff. There are a number of rainwater management systems, including modular rainwater harvesting tank, green roofs, rain gardens, and permeable pavement. Rainwater harvesting systems allow rainwater to be collected and stored for non-drinking purposes such as toilet flushing, irrigation, cooling tower makeup water, and wash-bay water.
