Automotive Ignition Coil Bobbin Molds

Automotive Ignition Coil Bobbin Molds are a type of highly specialized mold product. Ignition coil bobbins are divided into high-voltage coil bobbins (secondary bobbins) and low-voltage coil bobbins (primary bobbins). Since the coil bobbins in such products generally use PPO or PPS materials with poor fluidity, molding is relatively difficult. They have high dimensional requirements and relatively complex structures. Even the deviation at the mold joint line must not exceed 0.03mm, achieving almost no tactile feeling. The deviation in wall thickness cannot exceed 0.05mm. Moreover, each spacer of the bobbin must also be smooth without deviation and burrs. Any burr or deviation may cause jumping during wire winding and lead to the breakage of thin wires. Therefore, it has very high requirements for mold structure design, processing precision, high temperature resistance, impact resistance, and corrosion resistance. Moreover, both the ignition coil housing and plug are molds with inserts，In particular, the plug mold has a special structure and requires pre-embedded pins. Some structures have angles, making mold structure design relatively difficult. So most mold factories will find it difficult to be competent if they do not have experience in making such molds. However, this is exactly our company's advantageous mold project and also a major exported mold variety. Our company has 20 years of experience in making molds for automotive ignition coil peripherals. We have an industry-leading level in mold design, material selection, processing technology, mold life, and later maintenance. Moreover, we have supporting resources for coil-related accessories and materials in China, which can better provide you with all-round services.

Our company was established in 2004. For 20 years, we have been focusing on plastic injection mold design, mold manufacturing, parts processing, and precision injection molding. All technical personnel have more than 10 years of experience. In the long-term production process, we have encountered and solved various related problems and accumulated rich experience in injection mold design.
