Short Shot Injection Molding

Insufficient injection is also called short shot. Short shot is the phenomenon of partly incomplete at the end of the material flow, or a part of the cavity filled with dissatisfaction, especially the thin wall area or the end area of the the runner when injection molding. 

When the melt is cooled down without filling the mold cavity, or the melt does not fill completely after running into the cavity, it is called the short shot injection molding.

The main reason for short shot is that the flow resistance is too large, which makes the melt unable to continue to flow. The factors which impact the melt flow length including: 
* wall thickness of parts,
* mold temperature, 
* injection pressure, 
* melt temperature and material composition. 

If these factors are not handled properly, they will result in short shot.

What is 'Catch hook and thin-wall' of plastic mold products?

What is 'Catch hook and thin-wall' of  plastic mold products ?​ 1. The Catch hook The catch surface and the amount of catch hook are the important basis for the test data during assembe.  Once made any tiny mistake about these numbers, It would become a huge mistake of the product. Therefore, during mould design, We needs to pay special attentin to the catch hook assembly and testing. 2. The thin-wall What is the big problem about thin wall? The binding point is particularly easy to press and brittle, Then could't pass the test. It will be difficult to assemble in the next step, The product will be uneven filling, shrink, and easy broken.

Useful Tips for Custom Titanium Manufacturing

  JY Machinery offers high-quality precision and cost-effective CNC machining services for   custom titanium parts   to enhance manufacturing efficiency. Custom Titanium alloy manufacturing is mainly used for the production of aircraft engine compressor components, followed by the structural parts of rockets, missiles and high-speed aircraft, and related medical accessories. The density of titanium alloy is generally about 4.51g/cm3, which is only 60% of steel. The density of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much greater than other metal structural materials, and parts with high unit strength, good rigidity and light weight can be produced. The aircraft's engine components, skeleton, skin, fasteners and landing gear all use titanium alloys. The Reasons Why Titanium Is Hard to Machine If you want t...
