Semi-Precious Stone Earrings–A Fresh Alternative

/in , , /by

Color in jewelry enhances a wardrobe, but if you don’t want to wear costume jewelry–or if you cannot wear it due to metal sensitivities–consider fashion jewelry.  And not just fashion jewelry–handmade fashion jewelry with natural elements.

Fashion jewelry?  Quality jewelry made with components that are sterling silver, gold, or gold-filled.  Natural elements?  Yes, natural elements–semi-precious stones, nuts, seeds–with an endless variety.

Have you sworn not to wear costume jewelry?  Are you a little skeptical about the quality of jewelry that is handmade or jewelry that is not classified as fine jewelry?  Let me introduce you to some beautiful, semi-precious stones that will give you something to think about when it comes to quality fashion jewelry.

Semi-precious stone earrings are just one option of components for jewelry that is natural.  The colors and shapes of semi-precious stones are endless.

Are you looking for pink accessories?  Pink rhodonite stone earrings are absolutely lovely.  Rhodonite is a beautiful pink stone (Rhodon is Greek for rose) that appears to have black veins running through it.  The rhodonite stone is feminine yet very durable, and it comes in a variety of shapes.   You will find quality handmade rhodonite earrings available with sterling silver or gold-filled ear wires.

Or perhaps you want beautiful earrings for your black cocktail dress. Consider handmade rainbow obsidian earrings.  Rainbow obsidian is black–a by-product of lava.  This beautiful stone shows flashes of black, blue and green–casting off a beautiful iridescence in the light; hence it’s name: rainbow obsidian.  Rainbow obsidian handmade earrings and cocktail hour make a perfect match.

Are you casually dressed in red?  Have ever seen handmade red sponge coral earrings? Sponge coral is porous like a sponge.  If you really like the natural, organic look, you’ll love sponge coral earrings.  When they are handmade, these casual but classy earrings can be found in sterling silver and gold-filled ear wires.

Blue lapis.  Blue lapis stone earrings are a favorite with women who like semi-precious stone jewelry.  Whether you’re dressing up or down, these vibrant blue earrings will gorgeously accessorize your wardrobe.

The beauty of natural stones far surpasses anything that costume jewelry has to offer.  Expand your jewelry collection, but don’t leave nature out this time.  Consider quality, handmade jewelry with natural elements.  If you’re uncomfortable, ease into it with semi-precious stones.  You won’t regret the move.

Aluminum die casting design

/in , , , , , , /by

1.    There are a variety of casting methods to produce aluminum die casting and magnesium alloy casting, because of the low melting point of aluminum and magnesium alloy. So in the design of their structures, you should consider which kind of casting method to cast this casting at first, in order to consider the relative structural manufacturability.
2.    The aluminum alloy and magnesium alloy casting should try to use thin wall structure, and strive to the balance of wall thickness. This is helpful to prevent shrinkage cavity shrinking and improve the strength of the metal castings. But you can also thicken some part for the unbalance of wall thickness to set feeding aluminum and magnesium alloy casting. This can help filling shrinkage to guarantee the quality.
3.    The aluminum and the magnesium alloy is easy for oxidation and suction. The density is small, so as to make the static pressure of the metal fluid is small and be difficult to exhaust. Therefore, aluminum and magnesium alloy casting is easy to generate hole and oxidation slag, reduce the mechanical properties and gas tightness. So designing the casting structure should avoid big plane, and the transition should be gentle, and avoid causing the turbulence of metal liquid.
4.    Because of the low melting point of the aluminum and the magnesium alloy, to those castings that have some certain gas tightness requirements, you should avoid using core support to fixed core when design.
5.    The compression strength of magnesium alloy is higher than its tensile strength. So you should adopt asymmetrical section and box to undertake the compressive stress.
6.    Pay attention to adopting the method of double metal die casting and potting casting to solve the problems in the structural design of the aluminum alloy and magnesium alloy.
7.    The corrosion resistant of magnesium alloy is poor. Often use surface treatment to improve the corrosion resistance of magnesium alloy castings.

Mold manufacturer China

We are a professional Plastic mold manufacturer China company located mold Town–Huangyan. Established in 1999, we have been striving to study, develop, injection mold, blow mold, injection molding machine,blow molding machine and relevant products. Up to now, we have around 60 skilled workers, 20 engineers and a factory, which covers 2000M2 area.

In the mold designing course, some 2D or 3D software (such as AutoCAD, SolidWorks, Pro-E and so on) applied for assisting in designing, pre-making etc. Before mold is put into physical making, the MoldFlow software will be adopted to analyze such course to make sure if it is rational and workable. In the making course, there is a set of making method< system design, individual making, concentrate assembling, scientific managing> to help us improving mold quantity and service life. Up to now, we have created some plastic molds whose cycle time are over 1,000,000; die casting mold, over 400,000.

Our molds have been sold to U.S.A. German, Italy , Malaysia, Iran , Indonesia ,Africa and so on. Meanwhile, we have established good business cooperation with many overseas companies. Look into the future, we will be at the principle of ‘scientific designing, wonderful making technical, accurately assembling’ to continuously improve our mold structure, machine technical, mold material and hot process technical and so on. ‘Making the toppest products, achieve the best benefit for our client’ is our top aim.
