Dongguan Enuo mold Co., Ltd is a subsidiary of Hong Kong BHD Group, the core business is injection mold manufacturing and injection molding. Furthermore, Enuo mold is also an OEM factory engaged in inspection fixture/Gauge R&D, Die casting, CNC machining, Prototype products R&D, Parts spraying and assembly.
The mould consists of two primary components, the injection mould (A plate) and the ejector mould (B plate). These components are also referred to as moulder and mouldmaker. Plastic resin enters the mould through a sprue or gate in the injection mould; the sprue bushing is to seal tightly against the nozzle of the injection barrel of the moulding machine and to allow molten plastic to flow from the barrel into the mould, also known as the cavity. The sprue bushing directs the molten plastic to the cavity img through channels that are machined into the faces of the A and B plates. These channels allow plastic to run along them, so they are referred to as runners. The molten plastic flows through the runner and enters one or more specialised gates and into the cavity geometry to form the desired part.
While estimating the original native population of North America at the time of European contact is difficult, an attempt was made in the early part of the twentieth century by James Mooney using historic records to estimate the indigenous population north of Mexico in 1600. In more recent years, Douglas H. Ubelaker of the Smithsonian Institution has updated these figures. While Ubelaker estimated that there was a population of 92,916 in the south Atlantic states and a population of 473,616 in the Gulf states, most academics regard the figure as too low.
