hot runner system is used for production of large parts or long flow length. It saves material, lowers the part cost, improves part quality, shortens the cycle time, and improves production yield. […]
in addition typical machining activities, the mold manufacturing process includes a large amount of effort for purchase and assembly of standard components such as mold base, ejector pin, and ejector plate. […]
many standard mold bases are available in the market, with a wide complete range of models and cost. LKM, a major supplier for standard mold bases, classifies it’s standard mold bases into 3 categories: […]
there exist several parting line designs, considering various plastic part shape, it’s appearance, and ejection method chosen for the mold. […]
the material is selected for the part molding area according to the surface roughness of the plastic part and the expected number of injection cycles. […]
each mold grade has an unique reference manufacturing process. molds designed for higher injection repetitions demand better mold material quality with higher wear resistance. […]
in addition to the basic mold structure, other mold structures may be considered for a special plastic product, […]
side core-pulling mechanism coefficient for plastic parts with edge holes and groove, the mold structure usually has a side core-pulling mechanism, […]
molds have a complex structure and many features. It is difficult to enlist all of them at the time of quotation. Also it is difficult to adjust the parameters, […]
mold structure is rather complex, many of it’s features have a direct impact to it’s cost. Furthermore, some parameters are not available in detail at the time of quotation, until a design for manufacturing analysis is conducted.
