A Brief History of Building Blocks

Building blocks have been around in some form since ancient civilizations, but plastic interlocking blocks as we know them today trace their origins to the mid-20th century.

In 1949, the LEGO Group in Denmark began producing automatic binding bricks made of cellulose acetate, an early thermoplastic. These early plastic blocks allowed for better form-fit assembly than traditional wooden blocks thanks to patented interlocking studs and tubes.

LEGO started using modern acrylonitrile butadiene styrene (ABS) plastic in 1963. ABS offered improved elasticity and dimensional stability for a tight clamping effect.

Over the next few decades, LEGO released iconic sets like LEGO DUPLO for younger builders in 1969 and LEGO CITY in 1978. The LEGO SYSTEM OF PLAY launched in 1977 allowed pieces from different sets to interlock seamlessly, enabling unlimited creativity and variability.

Since then, LEGO has become by far the largest plastic building block manufacturer in the world. However many other companies have produced similar building toys over the decades, with more emphasis on education or sustainability.

The popularity of plastic building blocks continues today, both as a fun kid’s toy for free play and an educational toy for developing critical skills.

Types of Plastic Building Blocks

There is a diverse array of plastic building blocks available today, but they fall into a few main categories:

Cuboid-Shaped Building Blocks

The classic cuboid bricks made famous by LEGO are one of the most iconic plastic building blocks. They come in a range of colors and sizes, typically snapped together by studs and tubes. The cuboid shape and modular system allow for sturdy construction and unlimited possibilities.

Basic Building Blocks

These larger, chunkier blocks in simple geometric shapes make construction easy for younger builders. Brands like Mega Bloks and Duplo (LEGO’s version) offer good starter sets.

Classic Building Bricks

Vintage-looking sets like K’Nex’s Lincoln Logs, Tinkertoys, and wood-textured blocks evoke nostalgia while still being fun to play with. These make good open-ended gift sets.

Alphabet/Number Blocks

Blocks engraved with letters, numbers, and symbols help kids learn basics while building. Some also have Braille for developing literacy.

Metallic Building Sets

Several companies like SuperKids make building sets with magnetic brass-, silver-, or steel-coated blocks. These allow for unique construction like jewelry, sculptures, and interactive toys.

How Plastic Building Blocks Are Manufactured

The most common material for plastic building blocks is acrylonitrile butadiene styrene (ABS), a durable thermoplastic polymer. Here is a quick overview of the manufacturing process:

  • Injection molding: Molten ABS plastic is injected into a mold under high pressure then rapidly cooled, creating solid ABS in the shape of a brick.
  • Ejection: The finished bricks are ejected from the mold by ejector pins.
  • Trimming: Excess plastic is trimmed off the bricks with revolving blades.
  • Testing: Dimensions, clutch power, and durability are tested against strict quality standards.
  • Printing: Decals, patterns, or numbers are printed onto the bricks as needed.
  • Packaging: Bricks are bagged up or packaged into sets.

ABS is used for its durability, grip, and ability to stick to itself (cohesiveness) while still being detachable. The special formulation provides just the right tensile strength and elasticity for bricks to hold together securely while not being too stiff.

High-precision molds and automation produce plastic bricks with very tight dimensional tolerances for consistent clutch power and perfect interlocking ability. This innovative manufacturing process allows the mass production of plastic building blocks around the world.

Plastic building blocks are manufactured using an intricate injection molding process that produces precise, durable bricks.
