A professional speaker manufacturer has long been plagued by low production efficiency of magnetic circuit components, production capacity can not keep up with the demand for orders, especially in the processing of the core components of the magnetic circuit of the speaker, the drying process of the traditional equipment takes more than 15 minutes, which not only prolongs the overall production cycle, but also leads to a serious buildup of work-in-progress, and the production capacity of the magnetic circuit components in a single day is only 800PCS, which is far from being able to satisfy the downstream customers' batch orders of stereos and car stereos. The demand of downstream audio, car audio and other customers for bulk orders can not be met. What's more, due to the various specifications of U shells and magnets in the magnetic circuit of speakers, the adaptability of traditional equipment to different sizes is poor, which often leads to misalignment of the assembly of magnetic circuit components due to dimensional deviation, and the scrap rate is as high as 8%, which not only increases raw material loss, but also slows down the delivery schedule further.

In order to solve these pain points, the enterprise after many visits, and finally introduced the linear internal magnetic circuit machine double core. From the core parameters, the drying time of the drying oven of this equipment is only 8 minutes, compared with the traditional equipment to shorten the direct nearly 50%, significantly compressed the production cycle of the magnetic circuit assembly, reducing the pressure on the inventory of work-in-progress. The production capacity of 1200-1500PCS/H allows the enterprise to increase the production capacity of magnetic circuit assembly to more than 10000PCS in a single day, which can easily cope with the peak orders in peak seasons, and even undertake the large batch orders that have been given up due to insufficient capacity in the past.

In terms of size adaptability, the advantages of the linear internal magnetic circuit machine double core are particularly prominent. For the core components of the magnetic circuit of the speaker, the equipment supports the maximum size of the U shell within ∅40mm, the magnet and washer size covers the range of ∅9-∅30mm, which fully matches the needs of the high-end speaker magnetic circuit produced by the enterprise - whether it is used for small Bluetooth speakers of small size magnets of ∅9mm, or used for car speakers of large size magnets, the equipment can be accurately adapted without frequent adjustments to the mold or mold. ∅30mm magnets for car speakers, the equipment can be accurately adapted, without the need for frequent adjustments to molds or parameters, and the time to change the type has been reduced from 2 hours to 15 minutes, which greatly enhances the flexibility of production.

In addition, the internal magnetic circuit assembly solution and three-piece process flow carried by the equipment further optimize the production of horn magnetic circuit. Through standardized step-by-step design, the internal magnetic circuit assembly solution ensures the assembly precision of magnet, washer and U shell, avoiding the error of manual assembly and increasing the product qualification rate from 92% to 99%; while the three-piece process streamlines the whole process from raw material pre-processing to finished product inspection, reducing the intermediate redundancy and making the production rhythm smoother.
