Khi bắt đầu làm quen với các loại khuôn và hiểu cơ bản về quá trình tách khuôn, lắp ráp khuôn thì bạn cũng cần phải nâng cao hơn nữa khả năng của mình, và để nhanh nhất thì xem các loại kết cấu khuôn mà người khác đã làm, mình sẽ tận dụng lại các kết cấu khuôn đó, hoặc nếu giỏi hơn thì cải tiến tùy theo điều kiện cơ sở vật chất của công ty, bạn càng biết nhiều về các kết cấu khuôn nhựa thì bạn càng chủ động, vì có thể tận dụng thế mạnh của từng loại kết cấu khuôn vào chính thiết kế của mình.
NÓi thì dễ nhưng để nắm được thì cần thời gian rất lâu, bạn chỉ có thể thành công khi bỏ nhiều thời gian cho việc nghiên cứu và chọn lọc và dĩ nhiên cũng nên có sự giúp đở của những người đi trước, vì nếu đọc tài liệu khuôn nhựa này quá lâu mà vẫn chưa có giải pháp thì dễ nản chỉ hoặc hơn nữa là deadline đã qua thì không còn tác dụng nữa , và tìm công ty khác làm cho rồi,hi.
Tài liệu về các kết cấu khuôn là tập hơn hơn 130 bộ khuôn nhựa khác nhau, và được trình bày chủ yếu ở dạng bản vẽ, nếu bạn không rành về kỹ thuật thì cũng không thể đọc được những tài liệu này, do đó cân nhắc trước khi nghiên cứu để đỡ mất thời gian.
