Engineering Team for Proposing Development

Leave what “machines” can do to “machines.” “Humans” should do what only “humans” can do. Based on this policy, Suncall provides automation/laborsaving equipment and measurement systems that offer plenty of time for people who play an active role in various stages of production and that bring out the full potential of each individual to the maximum extent.
All parts of Suncall’s high-level product family and the technology supporting them are borne out of the creativity and research conducted by the employees themsleves. The experts in technology who set their focus on continuously evolving advanced technology are working on the development of products indispensable in the new era. The positive attitude each person devotes to his/her specialized field leads to the development of outstanding technology. We are an engineering team for the proposal of further development, and are always looking toward the future and pioneering new fields in a positive manner.

Inline Measurement System

Our measurement know-how cultivated through the production of high-precision parts is applied to various issues encountered on the production lines. We have built a total system that integrates control technology and an inline measurement system which combines Suncall’s original computer-based sensor-applied technology in order to improve quality and productivity dramatically.

Full-length Quality Assurance Using Eddy Current Equipment
[Quality Assurance by Nondestructive Tests Using Eddy Current Equipment]

Suncall performs full-length quality assurance by nondestructive tests using eddy current equipment, in order to take all possible measures against the variances in the quality of valve spring materials.
This method uses the principle of electromagnetic induction to examine the entire circumference and length of a wire to detect defects on the surface. Two types of inspection are employed to perform inline flaw detection in our wire-refinement process; one is the rotating probe method, which detects continuous flaws using a probe which rotates around the wire, and the other is the through-type coil method, which detects discontinuous flaws on the surface of wire by putting the wire through a cylinder-like coil.

State-of-the-Art Analysis Technology

Nowadays, HDDs are used widely not only in the mainframe computers used in the business world, but in consumer markets as well, such as game machines, video, pocket audio, and car navigation.
Requirements for HDDs will become strict in respect to large capacity, high speed, high reliability, and low pricing. Therefore, suspensions are demanded to have optional functions such as signal transfer and highly precise positioning, in addition to their functionality as sheet springs.
Suncall can satisfy such requirements from the market utilizing solely in-house technology to integrate system production in areas ranging from design and manufacturing to evaluation.
In the design process, required functions can be optimized by adjusting to the actual measurements made according to the methods of analysis informed by Suncall’s years of accumulated know-how. In manufacturing, we perform accuracy control using Suncall-made high-precision metallic molds that play a vital role in production. Furthermore, we have state-of-the-art evaluation equipment to supply mass-production products with consistent quality continuously.
