We have made it possible to perform barrel plating with trivalent chromium, which has traditionally been considered difficult.
Chrome plating, known for its beautiful white glossy appearance, high corrosion resistance, and excellent surface hardness, has been widely adopted in automotive parts, electrical products, and architectural hardware. However, it requires a jig set for plating, making it a process that cannot necessarily be said to be cost-effective or productive. Additionally, the use of environmentally harmful hexavalent chromium compounds in the plating process has led to manufacturers promoting green procurement to avoid it in recent times. To address these issues, Silvec has made it possible to perform barrel plating with trivalent chromium, which has traditionally been considered difficult. 【Applications】 - No use of hexavalent chromium compounds - Environmentally friendly - Significant cost reduction in jig costs and labor - The coating is hard and resistant to wear - Heat resistance → Equivalent to both trivalent and hexavalent chromium - Chemical resistance → Equivalent to both trivalent and hexavalent chromium For more details, please contact us or refer to the catalog.

RoHS directive compliant! Decorative plating utilizing the unique beautiful white glossy appearance of chrome.
Chrome plating can be broadly classified into two types: hard chrome plating (industrial chrome plating) and decorative chrome plating. Hard chrome plating involves plating chrome in a thickness range of 5μm to 500μm, and is used in products that take advantage of its wear resistance and low friction coefficient. Our chrome plating is decorative chrome plating, which involves nickel plating as a base layer and applying chrome plating in a thickness range of 0.25μm to 1.25μm. This decorative plating utilizes the unique beautiful white luster of chrome, which is highly corrosion-resistant, hard, wear-resistant, and has excellent durability against discoloration. 【Features】 ■ Compliant with RoHS Directive ■ Difficult to wrap around weak electrical components ■ Method: Using fixtures (static plating) ■ Applicable materials: Nickel-plated products *For more details, please refer to the PDF document or feel free to contact us. 【Contact Information】 TEL: 048-994-5931 FAX: 048-994-5935 E-mail: info@silvec.co.jp

Proposal for VE: High corrosion-resistant chrome plating "Alon Chrome Plating" for aluminum die-cast materials!
We would like to introduce a case where we solved the functional characteristics challenges faced by our customer and were adopted through a VE proposal. We received an inquiry from Company J, a connector manufacturer, regarding a connector housing for infrastructure, with the condition of plating on aluminum die casting (ADC 12) that meets "JIS neutral salt spray for 500 hours with no white rust formation." Among the conditions, there was a requirement not only for "corrosion resistance" but also for "no cracking due to crimping," which necessitated a coating with high ductility. We proposed our original technology, high corrosion-resistant chrome plating "Alon Chrome Plating," and through prototyping and evaluation, we achieved no rust formation after 500 hours of salt spray testing and no cracking during crimping, leading to mass production.

Electroless nickel plating for aluminum die casting! Introducing examples of quality improvement.
We would like to introduce a case study where we solved a quality issue faced by our customer using our plating and surface treatment technology. Company I, an aluminum die-casting company, was struggling with poor corrosion resistance of the inner diameter of their aluminum die-cast products that had an electric nickel plating + chrome plating specification. They visited us after inquiring through our website. We proposed electroless nickel plating and created a prototype with an electroless nickel plating + chrome plating specification. As a result of the JIS neutral salt spray test, the inner diameter passed with no white rust formation after 72 hours, leading to an order for mass production. [Case Study] ■ Company I, an aluminum die-casting company ■ Resolved Issue ・Improvement of aluminum die-casting corrosion resistance *For more details, please refer to the PDF document or feel free to contact us.
A. It is possible to perform plating that does not crack the nickel plating film even after crimping following electroplated nickel.
After nickel plating or nickel-chrome plating, we often receive inquiries about wanting to crimp and secure parts, but the plating film tends to crack. With our plating, it is possible to achieve a crimp-resistant nickel plating. The cause of cracking in nickel-chrome plating is the nickel plating film. Regular glossy nickel plating typically has a hardness of around HV550-600, and the film often cracks when bent or stretched during crimping. However, our nickel plating allows for a crimp-resistant nickel plating by depositing a plating film with good ductility. We can accommodate both barrel plating and jig plating.
Q&A: Q. Is trivalent chromium plating different from trivalent chromate treatment? A. Yes, they are different processes. I will explain the differences.
Trivalent chromium plating is a type of chromium plating that uses trivalent chromium compounds. Trivalent chromate is a chemical treatment. Chromium plating using trivalent chromium compounds such as chromium chloride or chromium sulfate is also a plating process that reduces trivalent chromium compounds to zero valence and precipitates them, so the plating film consists of metallic chromium and does not contain either trivalent or hexavalent chromium compounds. (It complies with the RoHS directive.) Trivalent chromium plating is commonly applied over nickel plating, and the substrate can be any metal that can be plated. Trivalent chromium chromate is a chemical treatment that scientifically generates a chemical film using trivalent chromium. The chemical treatment film using trivalent chromium compounds is a chemical treatment film formed by substances such as chromium hydroxide and chromium oxide (trivalent chromium compounds), so it does not contain hexavalent chromium compounds. (It complies with the RoHS directive.) By generating a film containing trivalent chromium compounds on the surface of zinc or aluminum, high corrosion resistance can be achieved. Generally, trivalent chromate is overwhelmingly used as a rust prevention treatment for iron after zinc plating. Our company can also directly apply trivalent chromate to aluminum.
Excellent solder wetting properties, with no worries about whisker formation! ~The appeal of this product revealed through comparisons with tin plating and tin alloy plating~
If you want to apply plating to soldered components or printed circuit boards, "tin plating," which has high solder wettability and excellent corrosion resistance, has been utilized as a very effective means. However, tin plating has the issue of whisker formation. Therefore, we would like to introduce our uniquely developed "solderable nickel plating." This plating has solder wettability equivalent to that of tin plating, but since it is an electroless nickel plating, there is no risk of whisker formation. In terms of whisker countermeasures, there are many tin alloy platings that add other metals to tin, which also have excellent solder wettability. *Examples: Tin-lead alloy plating, tin-silver alloy plating, tin-copper alloy plating, etc. Compared to those platings, our product has many appealing points such as "compliance with RoHS directives," "low cost," and "ease of plating." Although it is a new technology, it has received high evaluations in terms of performance and price, and we have numerous adoption records. If you have any concerns or requests, please feel free to contact us.
