20250346006 · 2025-11-13 ·

The invention belongs to the technical field of integrated machining of lenses and provides an integrated injection-molding method for a lens and a lens formed by the integrated injection-molding method to overcome the defect of poor sealing performance of lenses in the prior art caused by separate assembly of the lenses during production. In the invention, a high-transparency polycarbonate material is purified to remove impurities and moisture; then, an integrated mold is debugged; a material plasticization and filling process, a temperature holding process and a cooling process are accurately controlled by means of an injection molding machine to realize integrated formation of a lens and a product body; and after being formed, the product body is processed, and performance is detected. In this way, the sealing performance of the lens is improved.

METHOD AND APPARATUS FOR PROCESS MONITORING DURING PRODUCTION OF A FINISHED PART FROM A HOT-CROSSLINKING MATERIAL IN A PRIMARY SHAPING PROCESS

The invention relates to a method for process monitoring during production of a finished part (112) in a primary shaping process. The method comprises the following steps: a) providing at least one mould (114) designed for the primary shaping process, wherein the mould (114) has at least one cavity (116) for receiving at least one starting material for the hot-crosslinking material, and wherein an apparatus for determining a mould internal pressure is also integrated into the mould (114); b) heating the mould (114); c) introducing the at least one starting material for the hot-crosslinking material into the cavity (116) under pressure such that the finished part (112) is produced; d) detecting a progression of the mould internal pressure occurring in step c); e) differentiating, at least once or at least twice, the progression of the mould internal pressure in order to determine at least one derivative selected from the group consisting of: the first-order derivative and the second-order derivative; and f) characterising a progression of a chemical crosslinking reaction by means of at least one derivative selected from the group consisting of: the first-order derivative and the second-order derivative.
