The product is widely used in material development, quality assessment, defect analysis, etc. Its business involves multiple industries such as aerospace, automotive, electronics, energy, medical, etc. Focusing on achieving professionalism and providing customized professional metallographic solutions to customers is the core capability of Chuanhe.

Cutting

Good cutting is a beginning in perfect sample preparation.Cutting is an extracting without damage of material analysis area,it meets cutting demands of different materials by stable and reliable cutting equipment and suitable fixture and consumables.

Non-destructive cutting equipment can meet all kinds of material of different size and shaped working piece.Precision cutting machine has a high durability and easy-operation whether it is a automatic or manual.

Cutting discs, coolants and other consumables that meet the requirements of non-destructive extraction of various materials

Cutting fixture,working table and accessory are developed by different material and shape.

Mounting

Mounting is to embed irregular cutting extracted samples into a mold with resin to prepare them into regular standard metallographic samples.It is convenient for grinding,polishing, clamping and microscopic observation. According to the curing method of the resin, it is divided into hot mounting and cold mounting. Use appropriate mounting methods and corresponding resins for samples with different characteristics.

Whether it is hot mounting or cold mounting equipment, we can provide you with satisfactory mounting speed, mounting adhesion and size requirements While protecting the integrity of the sample.

A full range of hot mounting and cold mounting consumables to meet various mounting needs such as different curing time, hardness, transparency, shrinkage, conductivity, etc.

A variety of mounting accessories, such as auxiliary clamps, mold cups, release agents, etc.

Grinding & Polishing

Grinding and polishing is the most important part of metallographic sample preparation, the highest level is smoothness without marks. We can provide you with satisfactory grinding and polishing flatness and bright surface whether it is automatic with high reproducibility and consistency, or economical semi-automatic or manual grinding and polishing.

We can provide a smooth, stable and durable grinding and polishing machine whether it is a single sample grinding and polishing or a large number of large-capacity samples.

Including various high-performance grinding and polishing consumables that can replace imported ones, such as sandpaper, grinding discs, polishing cloths, polishing liquids, lubricants, etc.

Various clamps and levelers matching grinding and polishing machine.

Microscopic Analysis

Pictures are the truth, you can get the information when you see the picture. A good microscope is really needed for the curing sample preparation effect. The lighting system, objective lens and DCC camera chip, which are the determining factors of high-quality imaging of the microscope.They are all imported to achieve low-cost and high-definition optical microscopic imaging effects.

Preferred upright and inverted metallographic optical microscopes, DCC cameras and highly accurate analysis software.

Consumables used for microscopic observation, such as plasticine, AC paper replicas, and sample protection covers.

Microscope accessories, such as microscopic applanation instruments, loading platforms, etc.

Cutting disc depends on the cutting materials.

It is not only a guarantee of sample preparation but also a best way to save time and consumables to choose the suitable cutting disc.

Precision-Small Cutting Technology

Cutting disc adapts tireless rolling one-step forming technology combined new high-strength adhesive.It achieve three features of the cutting disc like flatness,high-strength and slim.

Stable cutting,Durable.

It won’t make sample heat damage when cutting disc shakes in the cutting process whatever the material is soft or hard and multi-shaped.

Four-in-one Cutting Fluid

Integrated cooling, lubrication, rust prevention and sterilization four-in-one functions can extend the lifetime of cutting disc in highly possible maximum.

How to come true the perfect sample preparation in your material?

Truer has abundant experience in sample preparation of different materials.We do the manual according to the common materials to help you know the preparation method fastly and precisely,avoid the problem in preparation process.

Sample Preparation of Titanium and Titanium Alloys

Titanium and titanium alloys usually adapt cooling mounting.

Heat mounting may can produce the hydrogen pollution and the metastable βphase will decompose because the hydrogen in the mounting material may diffuse into the sample in the hot state.Since the solubility of hydrogen in the α phase is extremely low, the solubility increases when the temperature rises, and the solubility decreases when cooling, resulting in the precipitation of tiny dispersed titanium hydrides.

Polishing Suspension

The high-purity materials are preferred whether it is diamond suspension or oxide polishing liquid, cause it has high grinding rate and removal rate.

Cutting Method

Cutting machine, fixture ,cutting wheel,cooling liquid and a series parameter(include the cutting mode,feeding speed and rotation speed) combined together determine the quality of the cut
