一, whether injection molds belong to standard parts
In the industrial manufacturing system, standard parts are usually components that have the same characteristics, can be mass-produced, don't need to be redesigned for unique goods, and can be bought from stock and utilized in a variety of situations and equipment. Custom parts are made and built to meet the needs of a given application or product. They cannot be used in place of each other. When you use this concept on injection molds. Based on the product drawings, you need to figure out their size, shape, function, and how to mold them. When the structure of the product changes, the mold usually needs to be altered or changed a lot.
二,Injection molds must be tailored because of how they are designed.
The design of injection molds does not begin with the equipment itself; rather, it follows a conventional reverse engineering methodology that first establishes the shape, structure, and performance specifications of plastic items, subsequently inferring the mold structure from these criteria. Any differences in the contour of the surface, the thickness of the walls, the design of the reinforcement ribs, the inverted structure, the way the parts fit together, and the surface treatment needs of plastic products will directly affect the layout of the parting surface, the structure of the cavity core, the shape of the gate, the method of ejection, and the design of the cooling system of the mold. The variances in mold design will also get bigger since different types of plastic materials shrink at different rates, flow differently, and have distinct molding windows.
三,Why do injection molds include a lot of standard parts but still have custom parts?
When making injection molds, parts including guide posts, guide sleeves, ejector pins, drivers, springs, fasteners, and mold frames frequently come from well-established systems of standard parts. These parts have the same standards, are always of good quality, and can be chosen and utilized right away. This is also a big reason why a lot of people think that injection molds are standard parts. In truth, standard parts only exist to make mold making more efficient, cut costs, and make it easier to fix things later. They don't say if the mold has universal qualities. The most important parts of molds are always the cavities, cores, inserts, and casting, exhaust, and cooling systems. These parts must be totally redesigned and finely machined to fit the product.
四,The ultimate conclusion derived from the standpoint of industrial use and procurement.
In real-world industrial uses, the level of customization needed for injection molds varies greatly from one field to another. The construction of everyday items and packaging is rather straightforward, and the mold scheme can be used again to some extent. In areas like consumer electronics, medical devices, and automotive parts, however, the standards for accuracy, stability, and complicated structures are higher, which means that mold customisation needs to be deeper as well. But no matter how the application market changes, injection molds are clearly customizable when it comes to buying and using them. Customers don't buy a conventional product that can be readily replaced; they buy a set of long-term production tools that are only used for one product. From the standpoint of an all-encompassing industrial definition, design logic, structural composition, and procurement utilization, a definitive conclusion may be reached: injection molds, in their whole, are categorized as customized components, whereas standard components are extensively employed in the manufacturing process for assembly.
