There are more and more products specifically designed for children on the market. Because the needs of children's products are different from those of adults. Usually when designing children's products, safety and convenience of use are more considered.

The commonly used children's tricycle mould steels are 45#, 40Cr, P20, 2738, 2316, 718, NAK80, S136, etc. Generally, we suggest to use steel 718 and Shanghai Baosteel P20. Good mold structure design is the premise of a qualified mold manufacturing. The mold structure and product structure should be analyzed in all aspects, including mold draft angle, miniature of product surface, design of pouring system, design of exhaust system, design of cooling system, etc. The most important and most likely problems of these molds will be repeatedly tried in the mold structure design Proven.

The important points which we care about when we make chair molds: 1) We add as many cooling system as possible including the chair surface to ensure outstanding cooling performance. 2) We add wear plates with 45HRC above to guarantee the chair molds’ life. 3) We use steel with 30-33HRC. 4) We use high speed CNC machine to reach 0.02 mm precision.

Building blocks are usually cubic solid toys made of wood or plastic. They are usually decorated with letters or pictures on each surface. They are allowed to be arranged in different ways or for building activities. They can develop children's intelligence, be assembled into houses, animals and so on.
