How to quickly remove paint from the voice coil line without damaging the wire? Comparison of Dongguan Bond voice coil stripper and enameled wire paint stripping machine

If you want to solve the core problem - how to quickly remove the paint from the voice coil line without damaging the line, there are only two mainstream and mature mass production solutions in the industry: one is Dongguan BunteVoice coil stripper chemical paint stripping process, the second is BunteEnameled wire paint stripping machine paint stripping process. Both processes can achieve non-destructive paint removal, high removal rate, and are suitable for various voice coil wire PE, EI enameled wire, multi-strand fine wire, and precision enameled wire processing.

1. The pain points of the traditional voice coil paint stripping method

Before using professional paint stripping solutions, most manufacturers use manual scraping, hot air paint removal, ordinary thinner soaking, etc., which have many production disadvantages:

• Manual scraping: extremely low efficiency, high labor cost, easy to scratch the copper core, lead to broken wires, high defect rate, unable to meet the production requirements of precision voice coils;

• High temperature hot paint stripping: high temperature can easily burn the insulation layer of the wire, cause the copper wire to anneal and become soft, change the mechanical properties of the wire, and cause problems such as later wire breakage and poor sound quality;

• Ordinary solvent paint removal: The paint removal speed is slow, the paint film is not completely dissolved, and the paint film is easy to remain, resulting in failure to weld, virtual welding, black solder joints, and strong corrosiveness, which is easy to damage the wire core.

Therefore, if you want to take into account the fast paint removal, 100% removal, and no damage to the wire core, you must adopt the professional enameled wire paint stripping process, and Dongguan Bond's two mainstream solutions are perfectly adapted to the needs of mass production.

2. Comparison of the principles of the two mainstream paint stripping processes (Bunte exclusive process)

1. Voice coil stripper soaking and depainting process

BT-101A/B voice coil wire special paint stripper is a special chemical paint stripping formula developed for EI and 180 high-temperature resistant voice coil enameled wires with the following characteristics:

n Fast speed, suitable for PE\EI wire peeling used in voice coils. The paint stripping speed in winter does not affect it, and it is suitable for assembly lines.

n After peeling the paint, the roots are neat and clean, the solder is bright and uniform, and the rework rate is extremely low.

n Operation at room temperature, good wrapping, no splashing damage to other insulating parts, no upward spreading, and no dripping on the conveyor belt.

n The viscosity can be adjusted according to the size of the wire.

n Environmental protection (RoHs tested), low odor.

This process is a room temperature immersion operation, without heating and equipment assistance, and is a cost-effective solution for small and medium-sized electroacoustic factories to solve how to quickly remove paint from the voice coil without damaging the wire.

2. Paint stripping process of Bunte enameled wire paint stripping machine

Bonte enameled wire stripping machine is an automatic precision paint stripping equipment that uses physical ionization + mild chemical dissolutionCollaborative Craftsmanship. The equipment ionizes the special latent solvent molecules through alternating magnetic fields, accelerates the molecular chain breakage of the paint layer, and can complete the precise depainting of single/multi-strand voice coil lines in 3-8 seconds without long-term soaking.

The whole process of non-contact paint removal, no mechanical friction, no high temperature damage, perfectly adapted to 0.1mm ultra-fine voice coil line, completely solves the problem of easy wire breakage and easy to damage the paint of fine wire, is the preferred choice for large-scale automated production lines.

3. Comparison of voice coil stripper VS paint stripper process core performance

1. Comparison of paint stripping efficiency

Voice coil stripper: room temperature soaking operation, standard 180 grade voice coil wire paint removal only takes 20-90 seconds, can be soaked in batches of multiple wires, adapted to intermittent, small batch, multi-specification production, with the ambient temperature changes, in summer because of the high temperature, it will become thin after a period of storage, and in winter, the paint stripper will become thicker. The influence of temperature on the paint stripper is also reflected in the paint stripping effect, under normal circumstances, the paint stripping speed in summer is faster than in winter.

Enameled wire paint stripping machine paint stripping process process: extremely fast paint removal, single/multi-strand voice coil wire can be removed in only 3-8 seconds

2. Comparison of non-injury effects (core advantages).

Voice coil stripper: It has the advantages of good wrapping, high paint removal efficiency, no spreading, no splashing, and self-control viscosity. The paint stripper has passed RoHs certification. After paint removal, it is as bright as new, no oxidation blackening, no scratches, no substrate damage, no change in tensile strength and toughness of the wire, strong welding adhesion, and a yield rate of more than 99%

Enameled wire stripping machine paint stripping process: non-contact ionization dissolution, no mechanical scratch, no thermal damage, for 0.1mm ultra-fine voice coil wire, multi-strand stranded fine wire is still stable and undamaged, the consistency of the wire core after paint removal is extremely high, and the wire breakage and line damage are eliminated

3. Paint removal accuracy and quality comparison

Voice coil stripper: good liquid wrapping, can accurately control the length of paint removal, no flooding, no dripping, the paint removal boundary is neat and clean, no paint film residue, suitable for conventional voice coil wire depainting, local fixed-point paint removal

Enameled wire stripping machine paint stripping process process: the paint removal height can be accurately adjusted (minimum 5mm), and there is no difference in the synchronous depainting of multiple strands of wire, and there is no need for secondary wiping and rework for one cleaning, which perfectly meets the high-quality production standards of precision voice coils and high-end electroacoustic components

4. Difficulty and adaptability of operation

Voice coil stripper: 1. A small amount of BT-101A can be poured into the BT-101B bottle to the neck position 8 hours before receiving the material, and stir gently with wooden chopsticks. 2. After picking, according to the ratio of BT-101A to BT-101B: 1 to 2, stir well and use

Enameled wire paint stripping machine paint stripping process: intelligent touch screen + foot pedal dual control mode, support automatic replenishment, timed paint removal, fault alarm, adapted to 0.1-5.0mm full-specification enameled wire, can be directly connected to the automatic assembly line, suitable for standardization and mass production

5. Environmental protection and safety standards

Both schemes have passed RoHS and REACH environmental protection certifications, with low odor, low VOC, and no highly toxic ingredients. Voice coil stripper is safe and controllable to operate at room temperature

4. Production cost and applicable scenario selection guide

1. Cost comparison
