MasterSimon of Rapid Prototyping
Appearance Models
The advanced manufacturing technology behind your products
Based on the 35 years of product development experience accumulated by the founder of MasterSimon since 1984, he has led a team of professionals to serve numerous start-ups and large corporations, enabling the entire supply chain from development to mass production to be safely produced and manufactured in Taiwan. The founder and a group of experienced engineers review and analyze the appearance models.
3D printing cannot replace a team of experienced engineers
From 2010 to 2020, every country is developing, producing, and manufacturing 3D printing products. Of course, for non-precision size or special material verification, 3D printing is indeed a rapid prototyping option, but in terms of color, material, touch, and actual mass production weight, 3D printing cannot replace the review and analysis of appearance models by a team of experienced engineers with more than 35 years of experience.
From idea, design, and sketching...to mass production to bring the end customer's product to market successfully
Our team has rich experience in assisting our clients' designers from creativity, design, sketching...to mass production, and working with brands' design centers and design companies to achieve good teamwork to make products come true. To build a good relationship, we need not only good teamwork but also more empathy and originality, for the sake of the end customer how to smoothly bring the product to market is the biggest motivation.
The appearance model must present the greatest value in industrial design
From geometry and engineering drawings, we care about R-angles, C-angles, corners, arcs, ridges, and whether a plane is flat or not? Surface Treatment and Cosmetics of materials, how to present different surface variations, and color variations, this is the appearance model that must present the greatest value in industrial design.
"Creativity and design are made more beautiful by breakthroughs in process technology.
Products become brand marks because of rigorous process technology,
and cost control to win consumers' favor."

Mass production functional model, Product reliability, and On-time market launch
The strict process control and product confidentiality principle can be activated in Taiwan for the proprietary products of customers from Europe, America, Japan, Canada, Australia, and Israel. From BOM sheet to EVT prototyping and verification, NPI, DFM, cost analysis, yield analysis, and risk management are introduced in the process discussion of the functional model to ensure the assembly line goes online smoothly. Through a careful verification process that is close to the mass production functional model, product reliability and on-time market launch are the greatest values.
Perform critical product prototyping to mass production and turn start-ups from Start-Ups into core brand values
MasterSimon works hard to turn start-ups from Start-Ups into core brand values, and because MasterSimon exists to perform critical product prototyping to mass production, we strictly adhere to our OEM ethics of being a silent OEM and never revealing information about the end customer.
FAI First Article Inspection
- In the process of first production, the person in charge of the production line, inspectors should go to the production site to supervise and check the actual producer according to the production process, according to the current valid production process documents to complete the first piece, and to supervise and check each production process, problems found in a timely manner to correct and solve.
- The first production of regular production products and products produced by stopping and starting again must complete all production processes, and after the producer has passed the inspection and signed on the first piece card, then handed over to the inspector for first piece inspection. During the first piece inspection, the inspector should work with the person in charge of the production line to carry out the inspection according to the current valid drawings, lists, process documents and product requirements, and after passing the inspection, label the first piece of product and have it signed by the producer (or representative) and inspector on the first piece card. For the first piece of inspection due to larger changes to the product can be signed by the relevant personnel and inspection approval; first piece of inspection failed to immediately return, redo the first piece.
- The first batch production of new products and the semi-finished and finished products generated after the change of materials and specifications need to be inspected and confirmed.
- The first piece inspection should be done in time to make the first piece record and fill out the first piece confirmation.
- When quality problems are found in the production of the first piece, they should be reflected and handled in time, and the unqualified items should be reconfirmed. Only when the first piece is inspected and qualified, and the result is recorded on the first piece card, and the quality is approved by the inspector, can the production be organized.
- After the first part confirmation, the inspector can start the normal delivery inspection work.
Many special patented parts are available from EVT DVT PVT ..... Before preparing for mass production, both parties must establish a stable manufacturing process according to the engineering surface level specifications.
