Transparent structural parts, such as thick sheet blister parts, play an important role in many industries. Their design not only affects the aesthetics of the product, but is also directly related to the functionality and durability of the product. The following are some key points and precautions for the design of transparent structural parts.
First, the choice of materials is crucial. Transparent structural parts usually use materials with high light transmittance and good mechanical properties such as PMMA (plexiglass) and PC (polycarbonate). These materials not only ensure the transparency of the product, but also have certain cold resistance, corrosion resistance and insulation properties.
Secondly, the wall thickness should be considered during design. The wall thickness not only affects the strength of the product, but also affects the fluidity and shrinkage during injection molding. The wall thickness of transparent structural parts should be as uniform as possible to avoid sudden changes, so as to reduce deformation and stress concentration caused by uneven shrinkage. At the same time, the wall thickness should not be too thick to avoid increasing costs and affecting transparency.
In addition, the design of the demolding slope should not be ignored. Transparent structural parts need to be smoothly ejected from the mold after injection molding, so a reasonable demolding slope must be designed. The size of the slope depends on the shrinkage rate of the material and the dimensional accuracy requirements of the product. The demoulding slope of transparent parts should be appropriately increased to avoid scratches and deformation.
Corner fillet treatment is also a key link in the design of transparent structural parts. Rounded corners can not only improve the strength and rigidity of the product, but also improve the flow state of the plastic and reduce stress concentration. The use of rounded corners at the corners can avoid problems such as cracking and deformation of the product during use.
Finally, the assembly and functionality of the product should be considered during design. Transparent structural parts are usually used in conjunction with other components, so the design must ensure that the assembly gap is reasonable to avoid interference and assembly difficulties. At the same time, the use environment and functional requirements of the product should be fully considered to ensure that the design meets actual needs.
In short, the design of transparent structural parts requires comprehensive consideration of material selection, wall thickness, demoulding slope, rounded corner treatment, assembly and functionality. Only by doing this can a transparent structural part that is both beautiful and practical be designed.
