Precision Parts Manufacturing


Industries That Require Precision Parts Manufacturing

Precision Parts Manufacturing supplies several industries with critical components.  Aerospace, Automotive, Military / Ordnance, Medical and Consumer Electronics are just a few of the areas where a precision parts molder is a valuable supplier.

The majority of molded critical components are made by the precision injection molding process, using thermoplastic resins.  Engineering Resins are a group of thermoplastic materials that combine great strength with light weight to be a desirable material in a wide range of conditions, and still be economical.

Precision Molding Process

The quality of a final critical component from the precision parts manufacturing process depends on several parameters.  Three factors that greatly impact the quality of a precision part are the manufacturing parameters, the material characteristics, and the mold design.

Manufacturing Parameters

When a precision injection molder is presented with a part print, they must determine the best size press to run the parts in taking the press attributes including tonnage, and clamping pressure into consideration.  They must also consider the type of tool to build, and the molding conditions that would yield the most optimum processing conditions.

Auxiliary equipment must also be considered.   When a precision molder can use automation such as sprue pickers and conveyors, they can maintain a consistent process and reliably produce quality accepted parts.

Determining the optimal parameters for the molding process is necessary to ensure consistency and reliable product quality.

Material Characteristics

When choosing the best material for an application, engineers must consider all characteristics of several different thermoplastic resins to choose the most appropriate resin that will meet the strength and durability demands of the functionality of the part.

It is also important to maintain a strong relationship with your resin suppliers.  Most polymer supply companies have material experts on hand ready and willing to assist with new information, suggestions and/or simulations.

Mold Design

A quality precision injection molded part requires a quality precision injection mold.  A flawless mold is the key to reliably and consistently producing parts to customers’ specification.

In most cases, the injection molder will design the mold based on the part print received by the customer.  Molds for manufacturing precision parts can be complex and require the skills of a journeyman mold maker.  It is helpful to have journeyman mold makers in-house that will lead the tool design and communicate with the customer’s engineers during the design phase.

CAD software and mold flow analysis is used, which is an indispensable tool for any plastic injection molded part.  Mold flow analysis is an indispensable component of any plastic injection molding design project.

Quality Procedures of Precision Parts Molders

Precision Injection Molding for demanding industries requires the molder to follow necessary quality procedures.  Meeting ISO9001:2008, and compliant to TS/ISO16949, and AS9100 standards and practicing them daily is necessary for success with precision parts manufacturing.
