Aluminum plastic mold VS steel injection mold


   Conventional injection molding typically produces steel tools for millions of parts, however, manufacturing molds typically takes months and costs more. But what if production needs require less? This is the ideal place for aluminum molds.


Today Asia Billion will take you to understand the difference between “aluminum mold” and “steel mold”.


Small batch production with aluminum mold


1) Mold production and parts are completed in 15 days or less

2)The cost of mold manufacturing is low. From the current mold market: the aluminum alloy market is relatively more stable than the steel market, which is more conducive to the implementation of cost control. Aluminum molds are about 50% lighter than steel molds, so aluminum molds are superior to steel molds in manufacturing, equipment, and injection shop equipment adjustments. Transporting light molds eliminates the need for expensive lifting equipment (such as cranes and crane trucks), reducing manufacturing costs.

3)Rapid production of products with no more than 1,000 to 5,000 molds and less demanding product processes. Generally used for fast proofing, small batch products. Production quantities can reach 10,000 or more.

4)Single and multi-cavity molds: 1-, 2-, 4- and 8-cavity molds are available depending on part size and complexity.

5)Thermoplastic and thermoset materials are the same as mass-produced materials; more than 100 different materials can be used, including ABS, PC, PP, LCP, POM and liquid silicone rubber.

6)If it is damaged, no maintenance costs and mold replacement for life, improved heat dissipation, no need to use messy cooling lines

7)The aluminum mold is easy to machine and has high dimensional stability and excellent thermal conductivity, which can save up to 50% of the cooling time of the mold during production. With the development of the market, the current European and American markets gradually show the phenomenon that the aluminum mold replaces the steel film.



Steel Injection mold


1) Millions of parts are produced and mold production takes a long time

2) The cost of injection molds made of steel molds is high, but the cost is lower in mass production.

3)The steel mold has high hardness, and the injection mold has good wear resistance and long mold life.

4)Generally, it can produce at least 300,000 molds for long-term mass production.

5)Multi-cavity molds can be larger than 8 chambers

6)Can increase part complexity

7)Injection mold has good mirror polishing performance and high requirement for surface finishing
