New Energy Industry Solutions

SIPU Mechanical focuses on the research, development and production of customized non‑standard automation equipment and full‑automatic coil production lines for the global new‑energy industry. Our core products cover high‑precision winding machines, coil taping machines, pin‑inserting machines, soldering machines and complete production lines, which are widely used in the production of new‑energy power components, automotive charging components and various special‑purpose coils.

In the new‑energy industry, different functional coils face distinct technical requirements on winding density, wire‑arrangement precision, insulation performance and heat‑dissipation structure. Some coils require ultra‑tight and neat winding to ensure high‑voltage resistance, while others need reserved gaps for heat dissipation and allow relatively loose arrangement. According to these practical production standards, we have formed two mature customized winding solutions, which have been verified in real‑world coil manufacturing projects. Below are two typical cases based on our actual customized services.

Typical Customized New‑Energy Coil Winding Cases

Case 1: Dense Neat Winding Solution for High‑voltage DC Coils

High‑voltage DC coils are key core components in new‑energy power modules, which work under high‑voltage, high‑current and long‑time continuous operation conditions. To guarantee stable insulation performance, high voltage‑withstand capacity and long‑term reliability, these coils must adopt dense winding with extremely neat wire arrangement.

Our customized servo‑driven winding machine is designed for high‑precision dense winding scenarios. The equipment is equipped with constant‑tension wire‑feeding system and multi‑axis precise positioning structure, which effectively avoids wire crossing, overlapping and uneven arrangement during winding. Every layer of wire is arranged uniformly and closely, ensuring consistent coil structure and stable electrical performance. This solution can well meet the strict quality standards of new‑energy high‑voltage products.

Case 2: Non‑dense Loose Winding Solution for EV Charging Gun Coils

EV charging gun coils are important safety control components for new‑energy vehicle external charging equipment. During long‑time charging work, these coils will continuously generate heat. Therefore, non‑dense winding with reasonable gaps between wires is required for heat dissipation, and the wire arrangement does not need to be extremely neat like high‑voltage DC coils.

Our customized winding equipment optimizes the winding track and wire‑spacing control according to the characteristics of charging gun coils. While ensuring basic electrical performance and control sensitivity, the machine reserves enough heat‑dissipation space between coil turns. It greatly improves winding speed and production efficiency, perfectly adapting to mass‑production needs of EV charging gun coils for new‑energy vehicles.

Apart from single‑station customized winding machines, SIPU also provides one‑stop non‑standard automation solutions including coil taping, pin inserting and soldering processes. We can adjust equipment structure, control parameters, tension system and production layout strictly according to customers’ coil specifications, wire types, winding requirements and production capacity.

Our customized new‑energy coil equipment has been widely applied in new‑energy component manufacturing industry, exported to multiple overseas markets and recognized by global customers. With rich experience in non‑standard automation customization, mature winding technology and stable equipment quality, we keep providing reliable production equipment for new‑energy enterprises worldwide.

SIPU continues to upgrade winding precision, automation level and equipment stability. Our professional after‑sales team provides global technical support, equipment debugging, parameter adjustment and long‑term maintenance services, helping customers build efficient and stable new‑energy coil production lines.

FAQ

Q1: Can your winding machines support both dense winding and non‑dense winding?

A1: Yes. Our customized non‑standard winding equipment can freely switch between dense neat winding for high‑voltage DC coils and non‑dense loose winding for EV charging gun coils. We adjust tension control, wire‑spacing parameters and winding track according to your coil requirements.

Q2: What types of new‑energy coils can your customized equipment produce?

A2: We provide fully customized solutions for almost all kinds of new‑energy coils. The high‑voltage DC coils and EV charging gun coils shown above are typical samples. We need customers to provide coil samples or technical drawings for evaluation before designing the suitable equipment.

Q3: Can you customize winding machines according to our wire size and coil specifications?

A3: Absolutely. We customize equipment structure, servo system and control parameters based on your wire diameter, coil size, turns, winding density and production capacity.

Q4: What is the delivery time for customized non‑standard winding equipment?

A4: Normally 25–35 working days after confirming all technical parameters. For full‑automatic production lines, delivery time will be adjusted according to project scale.

Q5: Do you provide after‑sales service for overseas customers?

A5: Yes. We offer global technical support, remote debugging, parameter setting and long‑term maintenance guidance for all customized new‑energy industry equipment.
