Product Engineer, Germany

March 14, 2025

icon_reviews_star

The parts matched our drawings closely, and the critical dimensions were clearly documented in the inspection report. Communication was straightforward throughout the project.

Automotive Project Buyer, Mexico

December 29, 2025

icon_reviews_star

We ordered several large CNC-machined components for a concept vehicle. The parts arrived securely packed and were ready for trial assembly.

Startup Founder, United States

November 13, 2024

icon_reviews_star

We needed a functional prototype for an investor demonstration within a limited timeline. The team reviewed the design quickly and delivered a usable assembly on schedule.

Mechanical Designer, United Kingdom

February 17, 2026

icon_reviews_star

Several machining risks were identified before production. The DFM suggestions helped us simplify the design without changing the main function of the component.

Purchasing Manager, France

August 21, 2025

icon_reviews_star

Quotations were detailed and easy to understand. Material, surface treatment, lead time and shipping costs were clearly separated, which made internal approval easier.

Robotics Engineer, Canada

June 12, 2025

icon_reviews_star

The aluminum housings fitted correctly during assembly, and the hole positions remained consistent across the batch. We did not need additional rework.

Electronics Product Developer, Japan

March 11, 2026

icon_reviews_star

The team responded carefully to our revisions and kept the different drawing versions organized. This reduced the risk of producing from an outdated file.

Industrial Designer, Italy

August 20, 2024

icon_reviews_star

The prototype captured the intended shape and surface details well. The finishing team also matched the requested texture more closely than we expected.

R&D Manager, Australia

March 4, 2026

icon_reviews_star

We tested two materials before selecting the final option. The comparison samples helped us evaluate strength, appearance and machining performance more efficiently.

Medical Product Engineer, Netherlands

April 16, 2026

icon_reviews_star

The project required small features and controlled dimensions. The inspection feedback was clear, and the parts performed as expected during our internal evaluation.

Procurement Specialist, Spain

October 24, 2025

icon_reviews_star

Updates were provided at the main production stages, so we always knew whether the order was in machining, finishing or inspection.

Automation Equipment Manufacturer, Singapore

May 30, 2025

icon_reviews_star

The machined brackets were consistent across multiple orders. Repeatability was important for our equipment assembly, and the results remained stable.

Product Development Consultant, Sweden

March 23, 2023

icon_reviews_star

The team handled CNC machining, surface finishing and final assembly through one project contact. This saved us from coordinating with several separate suppliers.

Cooperation in a Wide Range of Industries

TOP Prototype has successfully partnered with and served over 3,000 companies, committed to delivering exceptional quality from prototype design to mass production.
