Free Sample Testing and Formula Confidentiality Agreement: Technical Trial Guide
Investing in industrial mixing and milling machinery requires empirical proof: catalog specifications and sales brochures cannot predict how your specific formulation behaves under shear.
Every chemical slurry possesses unique non-Newtonian rheology: thixotropic yield stress, dilatant shear-thickening risks, sensitive volatile carriers, or stubborn particle agglomeration.
Procurement committees and R&D directors must validate that target Hegman fineness, void-free density, and thermal limits are achievable before signing purchase contracts.
SMIDA operates an advanced slurry testing and analytical laboratory at our 6,800 square-meter headquarters in Shenzhen, China.
We invite prospective clients worldwide to submit formulation samples for free mixing, milling, and degassing trials — fully protected by legally binding Non-Disclosure Agreements (NDAs).
For proprietary material innovators developing cutting-edge electronic pastes, aerospace adhesives, or cosmetic creams, formula confidentiality is paramount.
Engineers are understandably cautious about sending proprietary samples to an equipment builder without ironclad legal safeguards.
At SMIDA, customer confidentiality is an absolute operational red line.
We execute bilateral NDAs, safeguard proprietary formulations without chemical reverse engineering, and destroy all residual test slurries immediately upon trial completion.
This practical guide explains our trial testing protocol, analytical deliverables, and formula protection framework.
Phase 1: Bilateral Non-Disclosure Agreement (NDA) Execution
Before a single gram of customer material is shipped or formulation details are discussed, SMIDA executes a bilateral NDA.
Our standard agreement protects your proprietary formulation, processing parameters, and commercial project scope under international contract law.
Clients may use SMIDA's standard bilateral NDA template or submit their corporate legal counsel's preferred format.
We treat all customer formulations strictly as generic functional raw materials, requiring only necessary safety handling data (such as SDS sheets for flammability and toxicity) rather than confidential chemical recipes.
Phase 2: Sample Preparation and Shenzhen Laboratory Dispatch
Once the legal agreement is executed, our application engineers provide sample shipping instructions and courier guidelines.
Most standard mixing, milling, and degassing trials require only 100 grams to 1 kilogram of sample material.
Clients ship samples directly to our Shenzhen testing facility via international courier (such as DHL, FedEx, or UPS) with proper commercial invoice documentation.
Upon arrival, materials are logged into our secure test registry and stored in climate-controlled lockers until scheduled trial runs.
Phase 3: Empirical Testing and Analytical Deliverables
Testing is conducted on calibrated production-representative machinery, including planetary centrifugal vacuum mixers (at 0.2 kPa) and precision three roll mills.
Application specialists execute controlled test matrices, optimizing revolution-to-rotation ratios, vacuum ramp timing, and roller nip gaps.
Following the trial run, our laboratory generates a comprehensive Empirical Trial Report.
This deliverable includes before-and-after Hegman grind gauge readings, high-magnification optical microscope images for void detection, and final density pycnometer measurements, accompanied by high-definition video of the trial run.

Frequently Asked Questions
What sample volume is required for a conclusive laboratory trial?
For benchtop planetary mixing and degassing, 100 to 300 grams is generally sufficient.
For three roll milling trials, 500 grams to 1 kilogram allows multi-pass gap calibration and Hegman gauge sampling.
Can clients witness the trial run live via high-definition video call?
Yes. We routinely host live streaming video trials where your R&D team directs trial parameters in real time and observes microscope readouts on screen.
