Electroless Nickel Plating - Corrosion Resistance of Plated Coatings
We will answer frequently asked questions regarding our specialty, electroless nickel plating! Q: Can you tell me about the corrosion resistance of the plating film? A: Generally, electroless nickel plating is said to have excellent corrosion resistance. However, when products coated with 5 to 8 μm of electroless nickel plating are subjected to salt spray tests, defects may appear at sharp edges. This issue occurs when there are defects such as cracks in the electroless nickel film. To improve corrosion resistance, a sufficient plating thickness is necessary. Please consult with our representative regarding the plating thickness. *We also accept prototypes, so feel free to consult with us.*
Non-electrolytic nickel plating - black plating film -
We will answer frequently asked questions regarding our specialty in electroless nickel plating! Q: Can you achieve a black plating finish? A: We do offer black plating as well. However, our black plating is achieved through alloying the plating layer, resulting in an interference color that appears black. It does not have light-blocking properties. *We also accept prototypes, so please feel free to consult with us.*
Electroless Nickel Plating - What Materials Can Be Plated?
We will answer frequently asked questions regarding our specialty, electroless nickel plating! Q: What materials can be plated?

Adding shielding functionality to lightweight resin. Plating process that suppresses noise from electronic devices, enhances signal stability, and improves operational reliability!
In electronic devices and automotive parts, electromagnetic waves (noise) generated from circuits pose a significant challenge as they can lead to malfunctions and decreased reliability of other signals and devices. The "plastic plating and resin plating (electromagnetic wave shielding)" offered by Heiwa Kogyo incorporates a metallic shielding mechanism through plating into lightweight and highly designed resin parts, providing a solution that directly contributes to noise elimination. In this process, plating that blocks and absorbs electromagnetic waves is applied to resin housings and exterior and interior parts of electronic devices, imparting the following functions: 【Features】 ■ Electromagnetic wave shielding effect: Reduces noise in electronic devices, supporting signal quality and stable operation of peripheral devices. ■ Electrostatic prevention function: Reduces the generation of static electricity, enhancing the safety and reliability of devices and parts. ■ Heat resistance, dust resistance, impact resistance, and scratch resistance: Achieves reliable parts that can withstand harsh operating environments. ■ For those facing the following challenges: - Experiencing "malfunctions due to noise" or "communication failures" in electronic devices. - Wanting to balance decorative and functional (shielding) aspects. - Seeking to further enhance reliability with heat resistance, dust resistance, impact resistance, etc. *For more details, please download the PDF or contact us.

Features of Silvec's copper plating
Characteristics of Silvec's Copper Plating 1. It excels in electrical conductivity, thermal conductivity, antibacterial properties, and electromagnetic wave shielding, making it widely used as a base plating for various types of plating. 2. Particularly due to its excellent electrical conductivity, it has become an indispensable plating in the electronics field. 3. Both jig use (static plating) and barrel plating (rotating plating) methods are possible.
Features of Silvec's Chrome Plating
Features of Silvec's Chrome Plating 1. The appearance of the underlying nickel plating is directly reflected in the appearance after chrome plating. For example, applying chrome plating to a product with glossy nickel plating that has been buff-polished will yield a mirror-like finish. Similarly, if the material is buff-polished and then chrome plated over velour nickel plating, the velour's matte texture will remain visible. 2. Compliant with the RoHS directive. (Although hexavalent chromium is used in the plating solution, it precipitates as metallic chromium in the product, allowing compliance with the RoHS directive.) 3. Hexavalent chromium plating is difficult to apply to areas such as weak electrical components, which may result in exposed nickel on the backside of complex shapes. Due to this characteristic, barrel plating is not permitted. In some cases, fine screws may be plated at the back with mesh attachment, but currently, our company only performs stationary plating using jigs. (Trivalent chromium plating can be done using a barrel.) 4. Method: Jig use (stationary plating)
Features of Silvec's Electroless Nickel Plating
Characteristics of non-electrolytic nickel plating: 1. The plating thickness is uniform regardless of product shape, allowing for high-quality requirements with dimensional accuracy (5-10% tolerance). 2. Lead-free and compliant with RoHS directives. 3. Corrosion resistance and wear resistance are superior to electroplated nickel. 4. Friction resistance is lower than that of electroplated nickel.
Case Study of Functional Characteristics Improvement of Silvec: Case 2
We will introduce examples of how we have solved the functional characteristics challenges faced by our customers and cases that have been adopted through VE proposals. Example 2: Nickel plating "Solderable Nickel Plating" with soldering strength equivalent to tin plating. ■ Company M related to electronic components A customer who was looking for a plating company that could provide nickel plating with solder wetting properties equivalent to tin for micro-sized components made of 42 alloy material to be soldered onto printed circuit boards without flux visited us through a recommendation from a chemical manufacturer. We proposed processing our "Solderable Nickel Plating" using barrel plating, conducted prototype trials, and received evaluations. We repeatedly tested various storage conditions before soldering, and consistently achieved stable high solder wetting properties, securing the desired soldering strength, which led to orders for mass production.
Quality Improvement Case of Silvec
This is an example of a quality issue faced by our customer that was resolved using our plating and surface treatment technology. Case 1: Nickel plating for soldering electronic components mounted on substrates without flux ■ Electronic component company M During product launch, there was instability in solder wettability when soldering small-sized components made of 42 alloy material onto substrates without flux. We received an inquiry from a major pharmaceutical manufacturer. We conducted a trial using our soldering nickel plating "Solderable Nickel Plating," and as a result of the evaluation, it was found that the solder wettability was stable and equivalent to that of tin, leading to mass production.
![[With data] Nickel plating of aluminum material in a barrel.](https://image.mono.ipros.com/public/product/image/8f1/2000809743/IPROS11338384895661264700.png?w=280&h=280)
Can you nickel plate aluminum material in barrels at Silvec?
Q: Is it possible to nickel plate aluminum material using a barrel? A: Yes, it is possible at our company. Depending on the shape and size of the aluminum, the cost-effectiveness of plating using jigs versus barrel plating will vary. We will review the product drawings and shapes to suggest which method would be more cost-effective, as well as discuss the differences in quality. In addition to the price difference, the performance benefits of having a complete plating coating without jig contact, and the effectiveness of barrel plating for tubular products in achieving plating on the inner diameter, are significant.
