  1. Resin model car

Resin casting is used to produce collectible and customized toys and figures like designer toys, garage kits and ball-jointed dolls, as well as scale models, either individual parts or entire models of objects like trains, aircraft or ships. They are generally produced in small quantities, from the tens to a few hundred copies, compared to injection-molded plastic figures which are produced in many thousands. Resin casting is more labor intensive than injection molding, and the soft molds used are worn down by each cast. The low initial investment cost of resin casting means that individual hobbyists can produce small runs for their own use, such as customization, while companies can use it to produce small runs for public sale. Quality of both original masters and resin castings varies due to differences in creator’s skill, as well as casting techniques.

Pros and cons:


1.1 The texture is fine and smooth, paint hard to fall off

1.2 Resin can have a better shape, offer tight shut lines

1.3 No zinc pest


1.4 door is sealed can not be opened

1.5 Resin models are verry expensive

1.6 much weaker structurally than die-cast zinc-metal


  1. Diecast model car

The term die-cast toy here refers to any toy or collectible model produced by using the die casting method of putting molten lead or zinc alloy in a mold to produce a particular shape. Such toys are made of metal, with plastic, rubber, glass, or other machined metal parts. Wholly plastic toys are made by a similar process of injection moulding, but the two methods are distinct because of the properties of the materials. The metal used in die-casting is either a lead alloy (used early on), or more commonly, Zamak (called Mazak in the UK), an alloy of zinc with small quantities of aluminium and copper. The terms white metal or pot metal are also used when applied to alloys based more on lead or iron. The most common die-cast vehicles are scale models of automobiles, aircraft, military vehicles, construction equipment, and trains, although almost anything can be produced by this method, like Monopoly game pieces, furniture handles, or metal garden sprinklers.

Pros and cons:


2.1 More exquisite details

2.2 Doors can be opened, some even the sunroof

2.3 Feel heavy on your hand


2.4 Diecast zinc deterioration(result in blistering, expansion, distortion, cracking and even total collapse of zinc castings)

In conclusion

Both resin and diecast model have their pros and cons, collectors can according your require to choose the model. For my suggestion is 1:43 model, resin is better. If you need more details of model, 1:18 paudi diecast model car is the best choice.

  1. I do not give up on the diecast. The resin ones have not yet conquered me.
    Miniatures that do not open doors and hoods, have no engine are like toy cars. I see many cheap RC cars with as much detail as the resin cars, but they also move and turn on the lights.

    I’m sorry, but I say no to resin cars.

    Long live to diecast!
