When designing and making the custom pins, we often think that the design of the custom pins is just the surface of the custom pins, and we concentrate on the beauty and fineness of the front surface. However, to make the completely perfect custom enamel pins, especially the middle and high-grade custom enamel pins, the perfect design of the back-face is equally important.

A custom pin is majorly composed of three parts: Surface, Back-face and Attachment;

-1) Surface: presenting the primary design points of a custom pin;

Mold Options: all the customized designs match with all newly-made molds;

-2) Back-face: presenting the secondary design points of a custom pin;

Mold Options:

  1. a) Using existing design with existing molds of the enamel pin manufacturer, no extra cost of new mold
  2. b) The customized design with newly-made mold, extra cost of newly-made mold will be charged;

-3) Attachment: actualizing the wearing-function of a custom pin;

Common use attachment types and special types are available;

In this article, let’s pay attention to back-face part; this article will help you learn the specialized knowledge of Different Styles with Different Back-faces.

-Brief Introduction

Firstly, let review 4 back-face cases of the custom pins (using existing design with existing molds):

There are three main applications on the back-faces: 1.Lines Effect (Includes Leather Lines & Checked Lines), 2.Electronic Spark (Dull Polished Effect) and 3. Smooth Face Effect

 

—Regular Collocation:

–Soft Enamel Pins & Hard Enamel Pins + Lines Effect Back-faces

A back-face with lines effect has the better sense of concavo-convex; the application will be more conducive to the overall matching of the custom pins;

 

–Metal Pins/3D Cast Pins/Large Size Pins + Electronic Spark Back-faces

A back-face with electronic spark has the frosted effect; the collocation will look more textured;

 

–Offset Printed Pins + Smooth Face Effect Back-faces

Due to craftwork limited; the collocation will look natural, poised and clean at the same time;

Meanwhile, except craftwork limited, you can combine the style and back-face for your preference, the effect with existing mold are all free for your option;

 

—Customized Marking Options

On above mentioned bases, you can also customize the design of the back-faces (Lines, Patterns, Characters, Number).

 

Option 1:  Marking by Mold Stamping (use newly-made mold)

Making a new back-face mold according to customer’s design, the new back-face mold is used in the first process of production, stamping or die-casting on the back-face of the metalwork; all custom pins apply the same design with same mold. The raised back marking is mainly applied for uniform formulae design, such as company name, logo, website and phone number (small area only).

 

Option 2:  Marking by Laser Engraving

Laser Engraving is a surface finish process, printed the words or pattern on the products, it is a kind of optical principle surface finish process, showing the required etched words or pattern; the laser engraving back marking is no need of a new mold, on the basis of end-products, engraving handling the custom pins one by one; it is requested the corresponding flat, non-patterned location be left in advance. It is mainly applied for personal tailor design, every custom pins has the different engraving back marking, such as unique serial number, different names, etc (small area only).

Application Example

If you need to create the custom pins with different names for your students or staffs, if you use the marking of mold stamping option so that each name need a set of newly-made mold, then the laser engraving is your best affordable choice;

 

-In-depth Introduction

-A. Lines Effect and Electronic Spark Effect mainly relates to die struck or die casting process;

–Die struck is a process of metal block being processed by the mold mounted on the press machine producing separation or plastic deformation to the metal block so that obtaining the required parts.

Note:

  1. The used existing molds or newly-made mold for back-face is placed at the upper mold position;
  2. The mold with already engraved lines effect (includes checked lines & leather lines) or your special customized raised backing marking;

 

–Die casting is the process of pouring the molten metal into the metal mold, applying external force to the mold while the liquid is transformed into solid.

Note: The back-face is electronic sparked with dull polished effect; a dense film is formed and covered on the custom pins back-face with electronic spark finish.

 

-B. Smooth Face Effect mainly relates to offset printing process;

Attention: the lines effect or the electronic spark is not available for the offset printed pins;

  1. The offset printing technology will use to print the design of surface directly onto the metal base and cut out to the needed shape.
  2. No need of die struck or die cast process, and if the process is used, the artwork’s surface will be destroyed after stamping;

Note: The ready-made metal base already has the smooth face with wire-drawing processed;


In a word, expect craftwork limited, the actual application on the back-faces (make a new mold or not) will all be in accordance with your needs and preferences.
