Since moulds have been expensive to manufacture, they were usually only used in mass production where thousands of parts were being produced. Typical moulds are constructed from hardened steel, pre-hardened steel, aluminium, and/or beryllium-copper alloy.  : 176 The choice of material to build a mould from is primarily one of economics; in general, steel moulds cost more to construct, but their longer lifespan will offset the higher initial cost over a higher number of parts made before wearing out. Pre-hardened steel moulds are less wear-resistant and are used for lower volume requirements or larger components; their typical steel hardness is 38–45 on the Rockwell-C scale . Hardened steel moulds are heat treated after machining; these are by far superior in terms of wear resistance and lifespan. Typical hardness ranges between 50 and 60 Rockwell-C (HRC). Aluminium moulds can cost substantially less, and when designed and machined with modern computerised equipment can be economical for moulding tens or even hundreds of thousands of parts. Beryllium copper is used in areas of the mould that require fast heat removal or areas that see the most shear heat generated.  : 176 The moulds can be manufactured either by CNC machining or by using electrical discharge machining processes.
You can overdose on hydrocodone taking any form of the medication, but it’s much more likely when combined with acetaminophen or another non-narcotic painkiller. Crushing the hydrocodone and either snorting it, or dissolving it in water and injecting it, increases your risk of overdose. Abusing hydrocodone pain medications, such as Vicodin, can result in acetaminophen overdose, especially if more than two pills are taken at a time. Plus, if you take hydrocodone regularly over time, you can expect symptoms of withdrawal from hydrocodone when you lower or stop dosing.
There are many ingredients that can be injected into the turkey to add flavor and moistness. Many variations of spiced or herbed liquids can be used, but other ingredients, such as sherry, wine, beer, flavored vinegar, and seasoned oil can be used as well. When mixing the flavoring liquid, be sure it does not include ingredients that may get may trapped in the needle of the syringe, such as herbs that are not finely crushed. If garlic or onion is to be added, it should be used in a liquid form. A little orange juice can be added to the flavoring liquid to act as a tenderizer. Do not make the flavoring too strong because it may overpower the turkey's flavor.
