01 / THE PROJECT

Building the capability
to make it in-house.

A Vietnam power industry customer wanted greater control over how its composite silicone rubber insulators were made.

Previously dependent on external suppliers, the customer needed more flexibility in delivery planning, product customization and production scheduling. Establishing local manufacturing meant bringing machinery, tooling, materials and operator knowledge together.

Yakows supported the move with a turnkey composite insulator production line: silicone injection molding equipment, custom molds, silicone rubber material matching, installation guidance, trial-production support and operator training.

After comparing suppliers and evaluating the technical scope, the customer selected Yakows as its project partner. Factory visits and direct technical discussions helped translate the customer’s requirements into a production plan suited to its local workshop.

THE STARTING POINT

External procurement

Finished insulators sourced from outside suppliers, with delivery and customization dependent on external production schedules.

THE PROJECT DIRECTION

In-house production capability

A coordinated manufacturing line with local operators, matched equipment and materials, and continued technical support.

02 / CUSTOMER BACKGROUND & CHALLENGES

From supplier dependence
to production ownership.

The customer serves Vietnam’s power infrastructure market, where composite silicone rubber insulators support transmission, distribution and electrical insulation applications.

External purchasing had met the customer’s earlier product needs, but urgent delivery requests and changing project specifications called for greater flexibility. Customization depended on the schedules and capabilities of outside manufacturers. The customer wanted to bring key production decisions closer to the local projects it served.

The investment therefore had a broader goal than acquiring machinery. It needed to establish a working manufacturing system and a team able to operate it: coordinated equipment and molds, suitable silicone compounds, practical processing guidance and access to ongoing technical support.

01 / SYSTEM INTEGRATION

A complete line that fits the factory

The customer needed equipment, tooling and material recommendations developed around the same product requirements. Workshop layout, installation conditions and production flow had to be considered together so each part of the line could work within the actual factory.

02 / MOLDING KNOWLEDGE

Turning equipment into a working process

New machinery also required practical molding knowledge. Machine setup, material preparation, mold operation and process adjustment needed to become part of a repeatable operator workflow, supported by guidance during installation and trial production.

03 / MOLD & MATERIAL

Matching product and processing needs

The insulator design had to be considered alongside mold structure and compound behavior. Material selection addressed processing stability, mechanical performance, electrical insulation and outdoor service requirements, while tooling had to support the intended product geometry and demolding process.

04 / PEOPLE & SUPPORT

Building confidence beyond installation

The local team needed practical training in production, mold care and troubleshooting. Continued material supply and technical communication were also part of the customer’s plan for developing manufacturing capability after the line was delivered.

03 / INTEGRATED ENGINEERING

Four disciplines.
One working line.

For composite insulator manufacturing, machine selection, mold design, compound behavior and process control need to work together. The project connected each of these decisions.

01 / EQUIPMENT

Silicone injection
molding equipment

Equipment configuration considered the insulator geometry, target output, molding requirements, available workshop space and installation conditions. The selection was developed around the customer’s production objectives and the practical requirements of silicone rubber injection molding.

Machine & workshop fit
02 / TOOLING

Custom insulator
molds

Custom mold design and manufacturing addressed the product profile, shed geometry, demolding requirements and production efficiency goals. Tooling decisions were coordinated with the selected equipment and silicone compound to support the intended manufacturing process.

Geometry & repeatability
03 / MATERIAL

シリコーンゴム
material matching

Compound selection considered mold filling, curing, mechanical properties, electrical insulation and outdoor service requirements. Yakows connected the material recommendation with the customer’s molding conditions and continued to support silicone rubber supply after project delivery.

Processing & performance
04 / PROCESS

Commissioning
& operator training

On-site guidance covered machine setup, mold testing, trial molding, operating procedures and mold care. Training helped operators understand material handling, process adjustment, product quality observation and practical troubleshooting during everyday production.

People & production readiness

Coordinating the interfaces between machine, mold and material

During planning, Yakows reviewed the site layout, production workflow and future expansion needs. Equipment configuration, mold development and material matching were discussed as connected decisions, helping the customer build a practical manufacturing system around its insulator products.

During commissioning, engineers and the local team worked through machine setup, material preparation, mold testing and trial-production adjustments. This connected the original production plan with the workshop’s operating conditions and gave operators practical experience with the system they would use.

04 / ON THE FACTORY FLOOR

Real equipment.
Real production conditions.

Yakows visited the customer’s facility to review the workshop, discuss line integration and support the move toward local insulator manufacturing.

The factory visit covered workshop layout, installation conditions, material movement, operator experience and future expansion requirements. Reviewing these details on site helped Yakows develop a production line proposal that could be implemented within the customer’s local factory conditions.

Technical discussions focused on equipment placement, insulator mold operation, raw material handling and preparation for trial production. The visit also provided an opportunity to discuss training needs and how the local team would manage the transition from purchased insulators to in-house manufacturing.

05 / PROJECT DELIVERY

Installation and trial production

Installation guidance connected equipment setup with mold testing, silicone material preparation and molding parameters. Trial production provided a practical setting for process adjustment and operator instruction, with close communication between Yakows engineers and the customer’s production team.

Training for everyday operation

Training extended beyond starting the machine. It covered material handling, injection molding operation, mold maintenance, basic troubleshooting and product quality observation. Follow-up technical communication helped the team continue learning as its production experience developed.

06 / MATERIAL & PROCESS FIT

The right compound.
The right process.

In a composite insulator line, the silicone compound must work inside the mold and perform in the finished housing. A material recommendation starts with both requirements.

For this project, material matching considered processing stability, insulation performance, weather resistance and mechanical strength. The mold and equipment also had to suit the compound’s processing behavior, connecting the needs of the finished insulator with the way it would be manufactured.
