Special Products custom manufactured to your specifications

Lamina has made special components for as long as it has manufactured a standard product line. For over 50 years, Lamina specials have been made with precision and delivered with consistent quality.

Special Die Springs and Heavy Duty Compression Springs

Special die springs and compression springs can be manufactured to your specifications. Our special compression springs can be manufactured to your choice of material, size, tolerances, and coatings. We can manufacture to military specifications. We will provide special inspections, certifications, and testing as required.

See our Heavy Duty Compression Springs flyer for more details.

Special Wear and Guide Components

Our ball-bearing retainers and flat wear and guide components can also be supplied as specials. See our Specials Capabilities flyer for more details.

If one of Anchor Lamina's standard components is not suited to your application, we can manufacture a special to meet your exact needs. Our standard components can be modified to suit or we can create a new part to your exact requirements.

Specials can be manufactured outside the diameter and length size range normally found on our standard products. Our special components can include any standard product feature. Additional options can include surface finish, coatings, special materials and welding processes.

We offer a two-week turnaround on made-to-order special pins and bushings. Please give us an opportunity to quote to your requirements.

Bronze Plating Services


Lamina has been bronze plating precision die and mold components for over 50 years. Because of their standard high quality, Lamina Bronze plated components have long been known for their excellent wearability. Anchor Lamina has recently expanded its services to include bronze plating.

Today, Lamina's bronze plating facility in Bellaire, Michigan is one of the largest dedicated bronze plating facilities in North America.

Bronze Plating Facilities

Lamina's modern bronze plating facility uses automated rack plating. Our bronze plating operation provides a complete metal finishing service. We offer process services for chemical cleaning, aqueous washing, degreasing, and regular sand blasting.

Lamina specializes in the bronze plating of wear surfaces on low and high carbon steel. Our bronze plating line can accommodate single part weights up to 400 lbs. (180 kg) and a part size envelope of 36" x 36" x 96 " (900 x 900 x 2400 mm). Our bronze plating (80% copper 15% tin, 5% trace elements) process can attain a controlled plating thickness in the range of 0.001 to 0.025 inch (0.025 to 0.64 mm). Bronze plating hardness of 70 Rb can be achieved.

Lamina's Bronze Plating operations provides complete process control, quality, testing and chemistry for our in-house metal finishing and electroplating. Complete automotive, aerospace, military and commercial testing and approvals are available.

Dayton Progress


Delivering a new level of quality services—Dayton today

Dayton Lamina has a long-time reputation as a quality manufacturer and a leader in the metal stamping industry. Today, however, our markets and the needs of our customers are changing more rapidly than ever. That means more new products, higher quality, and an even higher level of service and support.

Dayton maintains the industry's largest inventory of punches and other die-set stamping products; yet we are well known as innovators and developers of "special" tooling for unique manufacturing applications. Over the years, many of our "special" tools have been added to our extensive line of standard products.

Today, we are focusing more closely on the development and manufacture of this "special" tooling. We are taking a more proactive role in developing new applications. We are looking closely at emerging and developing markets. We are placing a stronger emphasis on working partnerships with our customers. And we are offering more new ideas–and more new products–than ever before.

Meeting the "special" tooling needs of today's manufacturers

Today's consumers demand more. More new products. Higher quality products. And often more products for less money.

In order to stay competitive–often to stay in business–today's manufacturers expect their suppliers to provide better, faster, and more cost-effective ways to produce and deliver those products.

If your company has "special" tooling needs, Dayton Lamina can help. We have the experience and resources to provide new product applications, improved in-plant quality and performance, and reduced operating costs.
