If you already sell a proven coolant or brake fluid product and want to switch suppliers or expand production capacity, matching the existing product specification is your top priority. However, formula replication for automotive fluids is not a simple copy job. It requires systematic lab testing and performance verification. GAFLE manufacturer offers specification matching service, and this article explains our standard workflow, test items and important limits for buyers.
Sample submission and background information collection The first step is sample delivery. You need to send sealed bottles of your reference fluid to our factory lab. Along with the sample, provide all known data: freezing point / boiling point, DOT grade, service life, target vehicle application, original manufacturer standard and market where this product is sold. The more data you provide, the faster our technicians can narrow down the matching direction. If you do not have technical sheets, sending only finished samples is also acceptable, and our lab will complete the full testing.
Lab testing and parameter analysis at our factory Once the sample arrives, our lab team starts the testing sequence. For coolant, we test freezing point, boiling point, pH value, reserve alkalinity, corrosion protection performance and compatibility with rubber parts. For brake fluid, we test dry boiling point, wet boiling point, kinematic viscosity, corrosion performance and seal compatibility. We record every indicator and build a target parameter sheet. It is important to note that we test performance indicators instead of extracting the exact chemical component ratio of patented formulations.
Trial sample production and iterative adjustment After building the target parameter list, our chemists adjust the raw material ratio to make the first matched trial sample. Our factory will send this sample to you for testing. You can run your own bench test, vehicle test or third-party lab test. If any indicator fails to meet your expectation, feed the test result back to us. Our technical team will modify the formula and prepare revised samples until the performance is close to your reference product. This iteration cycle usually takes several rounds for high-precision matching.
Important boundaries of specification matching service Our manufacturer matches performance specifications, and we will not copy protected, patented formulas. If your reference product uses exclusive patented additives that are not available on the open market, we cannot fully replicate it. All matched formulas produced by our factory belong to you after confirmation, and we will not sell this matched specification to other competing buyers under your brand agreement. We also cannot copy counterfeit products or products that violate local regulations.
FAQ
Q1: Can GAFLE factory match both coolant and brake fluid specifications from my sample?
A1: Yes, our lab supports specification matching for both antifreeze coolant and DOT series brake fluid.
Q2: How long does the whole specification matching process usually take?
A2: It depends on matching difficulty. Simple coolant or standard DOT brake fluid matching takes 2–4 weeks. Racing-grade brake fluid or EV special coolant may take longer.
Q3: Do I need to pay for the formula matching service?
A3: Sample testing and initial trial sample have related lab charges. The cost will be listed clearly on our quotation before we start the matching work.
Q4: Will the matched product look exactly the same color as my original sample?
A4: We will adjust dye color as close as possible. But minor color difference may exist while all core performance parameters stay consistent.
Q5: Can the matched formula pass the same third-party test as my original product?
A5: Yes, we can tune the formula to meet the same standard, and we can arrange third-party testing after you confirm the trial sample.
Q6: After matching, can I get the full technical sheet of the new formula from the manufacturer?
A6: Yes, once you approve the matched sample, our factory will provide the COA and technical data sheet of the formula for your sales and compliance use.
