Tesla's unmanned taxi without spray paint on its plastic body was officially offline CyberCab; The world's first large-size in-mold spraying exterior parts of ideal car were offline...... In recent years, the in-mold painting (IMC) process has become the core breakthrough track of high-end interior and exterior decoration manufacturing in automobile main engine factories. BMW, Volkswagen, Toyota and other head car companies also preempted the layout.

The unique feature of IMC process is that the injection molding of thermoplastic and polyurethane coating are completed synchronously in the mold to realize one-step manufacturing of substrate and functional coating. The advantage of this is that it can not only reduce consumables and labor costs, but also significantly reduce the emission of VOCs, and the dual advantages of environmental protection and cost reduction are fully improved. However, most enterprises are trapped in mass production difficulties when landing, and every test mode is a cost loss:

l thermoplastic substrate and thermosetting PUR paint are coupled with two materials, and the available process range is extremely narrow;

l during the filling process, the paint is cured in advance, and starving short shots frequently occur;

l melt wrapped gas retention cavity, finished product bubbles, gas lines defects frequently;

l It is difficult to accurately balance the temperature control and curing cooling cycle of the mold......

Repeated offline test mode not only pushes up the loss of molds, materials, and downtime, but also keeps the product yield fluctuating, directly slowing down the pace of large-scale implementation of new processes in enterprises.

In response to these problems, Germany's MAGMA brought SIGMASOFT®A complete set of virtual molding simulation solutions. The software builds a digital twin based on the mold, material and process, and completely simulates the two-component molding of the base material PUR paint: Lock the better process parameters through the DoE multi-variable test, and predict the cavitation, overflow, insufficient curing and other defects, optimize the flow passage exhaust, accurately calculate the cooling and curing cycle, give the equipment upgrade and material formula adjustment scheme, the simulation results fit the real object, reduce test mode loss from the source, stabilize the yield, compress Takt time.

If you are still worried about the high cost of test mode and unstable IMC mass production rate, the Jung online class from 14:00 to 15:00 on August 28, 2026 cannot be missed! Xu Heng, technical engineer of maigeba (Suzhou) Software Technology Co., Ltd., will be invited to live broadcast to disassemble the core logic of painting in the mold, share the wisdom grid, interior decoration strip mass production practice cases, and demonstrate the complete operation of the simulation on the spot, open interactive Q & A simultaneously. Sign up immediately to master the core technology of mass production of exterior decorative parts new technology in new energy vehicles.
