(1) The matrix material, geometry and size of the plated parts, and the value of the parts themselves;
(2) coating thickness, dimensional accuracy and coating performance;
(3) local electroplating or selective electroplating;
(4) Heat treatment or other special post-treatment of the coating;
(5) Quantity and batch of electroplated parts;
(6) delivery time, etc.
It can be seen that the price of electroless nickel plating is by no means the arithmetic product of unit price, plated area and coating thickness. In view of the above effects
Factors, the actual transaction price varies greatly. It is reported that during the period of 1984- 1987, the average price of electroless nickel plating on German steel was 600- 1 0,000 DM/the third generation electroless nickel plating price was 0.6-0.8 DM per square decimeter. The buyer has special needs.
Yes The price per square decimeter 10.urn is also common between 1 2 marks. In the domestic market, if the price of electroless nickel plating on steel parts is calculated as 1.82. 5 yuan/10ft d, the price of electroless nickel plating is about 2 297 3 185 yuan /kg.
In a word, electroless nickel plating is expensive, which is several times more expensive than electroplating nickel. Due to the excellent performance of electroless nickel plating, its cost performance is still very high. Similarly, the quality of electroless nickel plating is different, and the price will be different. Quality includes some extra costs, and quality control and quality achievements will be reflected in the price of products. The cost paid to ensure the satisfactory quality of users in the market, the so-called quality cost, will be a reasonable cost with high rate of return.
So how to calculate its cost?
Meeting users' technical requirements and reducing production cost are the driving force of quality control of electroless nickel plating, and the implementation of quality inspection itself is also the process of increasing production cost: cost factor is one of the important contents of electroless nickel plating, and it is also a very confusing problem for all parties at present. Generally speaking, the so-called cost is usually understood as all related expenses after the supplier is booked when the commodity exchange is completed; For the buyer, payment according to the value of goods becomes the beginning of the buyer's process cost. In our daily life, we often come into contact with the price, and we don't know how much it is worth. The same commodity can have different prices due to different objects, time and place. However, cost refers to spending this.
This fact has objective truth. After deducting the cost, the price constitutes a profit, which is the goal pursued by all parties in the market. The answer should be answered by accounting and marketing professionals.
There are two common expressions for the cost of electroless nickel plating on 1. One is the total cost of electroless nickel plating per unit area 10um. The other is the average weight gain 1kg of the total cost of electroless nickel plating. In the cost calculation model of electroless nickel plating by W ltiedel et al., the expression of the total cost k of the coating is: ik = σ f+σ vii, where F is the fixed cost, including factory equipment, labor wages, total management and operation expenses (sales, advertising), inspection expenses, etc. V is consumption cost, including chemicals, pretreatment, electroplating, finishing, energy consumption, electroplating bath wastewater discharge and treatment, etc. The model is based on plating Ni-P alloy coating with phosphorus content of 12% on steel substrate. Assuming that the volumes of three kinds of plating solutions are 200 L, 1 000 L.3 000 LI respectively, each shift is 8 hours, of which 2 hours is preparation time and 6 hours is electroplating time, and the total electroplating cost is estimated respectively. When the production scale is large and the equipment utilization rate is high, the fixed cost of the coating is low and the total cost of the coating will also be reduced. At this time, most of the total cost is consumable cost. Small workshop production. Because the fixed cost is relatively high, the total cost of coating is high, which is suitable for dealing with higher-priced business.
2 Cost of electroless nickel plating solution
Today, the service life of electroless nickel plating solution still exists. The cost of electroless nickel plating solution constitutes a considerable part of the cost of electroless nickel plating consumables. This paper attempts to evaluate the cost of typical electroless nickel plating solution according to the upper and lower price limits of commonly used chemicals at present. In addition to the different concentrations of chemicals used. The difference of chemical consumption cost is mainly caused by using different Luoshe Chongdang particles in different electroless nickel plating solutions. The market prices of different collateral and buffers vary greatly. Especially in the third generation electroless nickel plating solution, metal ions are no longer used as stabilizers, but organic compounds and inorganic compounds are used as composite stabilizers, and the chemical consumption cost is high. Of course. The consumption cost of chemicals includes not only the start-up cost of electroplating solution. It also includes supplementing and adjusting the chemical consumption of bath components, and the service life of bath also directly affects the cost of consumables. At present, most commercial electroless nickel plating solutions at home and abroad are sold in a group of concentrated solutions 4 or 5 times their own. In the effective life of high-tech commercial plating bath, the cumulative amount of concentrated solution consumed by supplementary adjustment is equivalent to 1.2 times the volume of open-pot plating bath. The consumption of supplementary adjustment corresponds to the output of electroless plating solution.
Yes, the slotting fee is a bit like the first investment in using commercial electroless plating solution, and the cost is definitely higher than that in the case of self-preparation, because the price of commercial plating solution includes the technical service and debt service of proprietary technology development investment. At present, the use cost of domestic commercial electroless plating solution is about 1.5 times higher than that of self-made plating solution, and the cost of using I=l plating solution is even higher. It is worth noting that up to now, most of the imported electroless nickel plating solutions sold in the domestic market belong to the second generation electroless nickel plating technology. Mature commercial technology provides good quality assurance, and the proportion of commercial plating solution used in electroless nickel plating in industrialized countries accounts for more than 80%; This situation in China is just the opposite, and it can't be said to be some kind of difference.
