Chemical nickel coating:
The nickel-phosphorus coating is created without the aid of electric current. It ensures an uniform layer on the surface and in the opening of the shape-complicated parts. It excels with high resistance to rust. We also offer the possibility of heat processing in the protective atmosphere and so achieve the coated layer hardness of min. 700HV.
Basic material |
steel, brass |
| Thickness of coated layer | 3 - 15 µm, otherwise on request |
| Max. dimens. of the parts | 600 x 400 x 300 |
| Application | engineering, parts for electrotechnic industry, car industry, etc. |
Galvanic copper plating:its is used as a pre-finish of the surface of steel parts before their tin-coating. This surface finish takes place in a drum-like device.
| Basic material |
steel |
| Thickness of plated layer | 1 - 5 µm, otherwise on request |
| Max. dimens. of the parts | small parts |
| Application | engineering, parts for electrotechnic industry, etc. |
Galvanic tin plating:Plating of high-gloss materials is carried out on a special line. We use food tin with pureness of 99,99%. The technology ensures high solderability. Super adhesion, spalling does not occur. High resistance to touch marks.
| Basic material |
steel, brass |
| Thickness of plated layer | 0,3 - 7 µm, otherwise on request |
| Max. dimens. of the parts | small parts, soldering ears, contacts, etc. |
| Application | engineering, parts for electrotechnics, decorative purposes etc. |
Galvanic silver plating:Depositing of silver coats of high pureness is carried out on a special line. For usage in electrotechnical industry, solderibility is ensured. If the silver is coated on steel, it is necessary to apply an intermediate layer of Cu.
| Basic material |
steel, brass |
| Thickness of plated layer | 0,3 - 5 µm, otherwise on request |
| Max. dimens. of the parts | small parts, soldering ears, contacts, etc.. |
| Application | electrotechnical parts, decorative purposes, etc. |
Galvanic zinc-plating:Applying of glossy layers of zinc with blue chrome passivation. Hanging method. Various complicated shapes possible. The layer does not crack. No peeling.
| Basic material |
steel, cast iron |
| Thickness of plated layer | 5 - 30 µm, jinak dle dohody |
| Max. dimens. of the parts | 1300 x 500 x 700 |
| Application | engineering |
Control documentation:
Our company has been awarded a certificate of quality management system acc. to ISO 9001. If requested, we are able to issue a protocol on layer thickness and other measurred values.
We also offer the possibility to make reference samples.
You are kindly requested to take advantage of our experts in the department of technology of surface finish.
2. Gauge manufacturing
In the tool-making workshop of LDM company, we manufacture roll, thread and calliper gauges. Each gauge is issued a protocol on its measuring.
3. Maintenance of tools
Further we offer sharpening of tools (wood working ones included), heat processing (hardening, case-hardening, annealing) and grit blasting (maximal weight is 1000 kg).
4. Waste disposal
We offer the possibility to take advantage of free capacity of our own licensed neutralization station. After providing us with specification of a substance to be disposed of together with its chemical analysis, we are able to proceed to final disposal.
All procedures with chemicals, surface finishing and operation of neutralization station are subject to supervision of authorized company Marius Pedersen a.s..
