In precision mold processing, surface quality directly determines product performance and service life. whileRoughness profilometerAs an important tool for detecting surface topography, its selection and brand choice are of vital importance. In the face of numerous roughness profilometer manufacturers in the market, how to screen out truly professional and reliable service partners? This article will, in light of the actual demands of mold processing, analyze for you the core points of choosing a roughness and profilometer manufacturer.
Even the slightest concavities, scratches or ripples on the mold surface can lead to difficulties in demolding injection molded parts and a decrease in the light transmittance of optical parts. The traditional stylus detection method is inefficient and may scratch soft molds. At this point, a non-contact, high-resolution roughness profilometer can play a crucial role.
For instance, the KLA Profile 3D white light interference profilometer employs vertical interference scanning (WLI) and phase interference (PSI) technologies, achieving a vertical resolution of sub-nanometer level (1nm). This means that it can clearly distinguish the atomic-level undulations on the mold surface, whether it is the roughness of mirror-polished molds (with Ra values as low as 0.05nm) or minute machining tool marks, none of them can hide.
Many roughness profilometer manufacturers mark very high parameters, but when actually measuring curved surfaces, highly reflective or large drop samples, the accuracy decreases. The Profilm3D provided by Unicon Technology Co., LTD. (Yiying Technology) has a single scanning field of view of up to 2mm (with a 10x objective lens). Through the automatic stitching function, it can obtain large-area topography while maintaining a step height accuracy of 0.1%. This is very practical for inspecting the complete surfaces of large automotive molds or micro precision gears.
The production pace of the mold factory is tight. Once there is a measurement deviation in the equipment, the roughness and profilometer manufacturer needs to respond promptly. Unicon Technology Co., LTD. (Yiying Technology) has branches or laboratories in Shanghai, Dongguan, Tianjin, Chengdu and other places, and promises 7× 24-hour online service and 8-hour rapid after-sales response. This service network density is a soft power that cannot be ignored when choosing a roughness profilometer manufacturer.
Before making a purchase, having the roughness profilometer manufacturer conduct actual measurements on your typical mold samples is the key to avoiding selection errors. Legitimate roughness and profilometer manufacturers such as Unicon offer free sample testing services. You can contact them and send the molds to be tested (such as optical molds with microstructures or stamping molds with deep narrow grooves) there to obtain the actual measurement data and 3D topography diagrams, and use the results to determine whether the equipment meets your requirements.
It is worth mentioning that high-precision roughness profilometers are highly sensitive to environmental vibrations. Even if the instrument itself is highly accurate, if it is placed in a workshop or laboratory bench with low-frequency vibration, the measurement results will be distorted. Therefore, professional roughness and profilometer manufacturers usually also provide corresponding vibration reduction solutions.
For example, the HERZ AVI-400 series active shock absorption system can effectively eliminate six degrees of freedom vibrations within the range of 1-200Hz, reducing external vibration interference to a level that does not affect the accuracy of the profilometer (system noise is lower than 50nG/√Hz). This means that you can directly install the profilometer near the production workshop without the need to modify the expensive vibration isolation foundation, thereby improving the detection efficiency. Choosing a roughness and profilometer manufacturer that can provide an overall solution of "detection instruments + environmental optimization" will make subsequent use more worry-free.
Taking the surface of typical die steel (such as S136 or SKD11) after finishing as an example, the Profilm3D profilometer is used to measure:
Conventional milling: The surface roughness Ra is usually between 0.8μm and 1.6μm. The profilometer can clearly display the periodic tool marks and feed traces left by the tool.
Precision grinding processing: Ra can be reduced to 0.1μm - 0.4μm, and the profilometer can assess the depth and distribution of residual abrasive grain scratches.
Mirror polishing mold: The Ra requirement is less than 0.02μm (20nm). The PSI mode of Profilm3D (RMS repeatability of 0.1nm) can accurately verify whether the mirror surface standard is met, avoiding visual misjudgment.
Through these specific data, roughness profilometer manufacturers can help mold enterprises establish quantitative standards from processing to acceptance, reducing delivery delays caused by surface quality disputes.
In conclusion, when choosing a roughness profilometer manufacturer, please pay close attention to the authenticity of its core technical parameters, local service capabilities, whether it offers free sample testing, and whether it can provide a vibration reduction solution.
