make sure your tolerance make sense
In order to make sure that the tolerances shown on the product drawing make sense and can be achieved. the mold designer must know molding characteristics of specified plastic well, […]
product designer and tolerance
Our product designers often make mistakes in assigning tolerance to the product that are not necessary for the function of product. The proper method is to give a relatively large general tolerance and tighten up dimensions only where it is necessary for the function of the product or where it is required in the assembly [...]
tolerance on the product drawing
Tolerances are probably the most important areas to be checked. When this project is quoted, the tolerance will be checked and question. Before designing, the final drawing released with complete tolerance should be required. because a large portion of the machining cost is directly related to the tolerance.
molding cycle
In order to achieve the shortest possible molding cycle, special cooling methods, added ejection features, special mold material and lubrication will be considered, on the other hand, some other elements may also have a significant impact on the molding cycle. For example Differences in the plastic, wall thicknesses, draft angles, methods of gating and so [...]
do you know anticipated molding cycle before mold design?
As for anticipated molding cycle, no matter our customers or mold makers always want to build a mold with shortest possible molding cycle. But making cost is a real problem. How to find a suitable solution to meet our customer requirement at a competitive price will be very important to every mold maker.
degraded material means waste
When any product contains even small portions of degraded material, it must be discarded, not only because of poor appearance of the product but physical properties may have been lost and the product will not perform as expected.
how to identify thermoplastic material degradation
how to identify thermoplastic material degradation? I want to say when all thermoplastic materials change color to yellow or brown at certain high temperatures over a length of time. it will be shown, And the ultimate form of degradation is when the plastic becomes charred and black.
which plastic characteristics will directly affect your mold design
Of course, a mold designer should know which plastic characteristics will directly affect your mold design, for example: […]
how to understand mold price
Occasionally, a mold maker try to offer a low price for a new mold project to customer as the result of a sales policy. For example, to win a new customer or to enter a new field of product in which the mold maker has little or no experience. Regardless of the low price, at [...]
what does a professional mold designer know before mold design?
As a professional mold designer, before designing, it is very important to understand all the parameters when quoting a price, if not, you may design a mold that greatly exceeds the quoted price. Note that the purpose of any industry is to make money with their product.
