Plastic Part Design to Avoid Sink and Warp

Plastic injection mold designers must consider the resin chosen for the part manufacturing when designing the mold as this plays a very important role in meeting part specifications.  One characteristic of the plastic material that requires careful consideration is the cooling rate compared to the geometry of the part.

 

What is Sink

This plays an important role in the likelihood of parts developing sinks or warps, and can have significant consequences on successfully molding parts with consistent results.  The cooling rate is extremely important because as the part begins to cool it will always begin at the mold surface and move inward, toward the center.  If the geometry of the part is such that the part is too thick, the center area of the part will not solidify quickly enough.  This center stays molten long enough for it to cause stress on the area already solidified, pulling downward towards the center and leaving a sink mark on the outer surface.  

 

Avoid Sink in Plastic Parts with This Rule of Thumb

 

Ribs are used to add strength to plastic parts in thin wall or critical areas, but can also cause sink marks on the exterior side of the part.  When designing plastic parts to avoid sink marks, remember the basic rule to keep the thickness of the rib somewhere around 60% the thickness of the wall.  Following this rule of thumb should help to avoid sink marks during the cooling process.  

 

What is Warp

 

If a plastic part design includes areas of uneven wall thickness, stress can develop during the cooling and solidifying stage.  If this stress is excessive, warps will occur where thinner sections solidify faster than thicker sections.  

 

Avoid Warp in Plastic Part Design

 

When undue stresses due to transitions in wall thickness occur, plastic part designers can combat this by using a ramp.  Designers also use gussets in corners of some geometric areas to help prevent warping.

Injection Mold Makers for Precision Parts Manufacturing

Injection molding companies that manufacture precision parts are often in need of a precision injection mold making company to add to their preferred vendor list.  Many quality and purchasing engineers in various industries are searching for a custom mold making company with high precision capabilities to manufacture critical components.

Some industries that require vendors with precision capabilities to produce to high performing parts and components are:

  • Automotive
  • Aerospace
  • Military / Ordnance
  • Medical / Pharmaceutical
  • Consumer Electronics

Suppliers to OEMs in these industries must meet stringent requirements, as all suppliers play a vital role in the quality of the end product.   An injection molder must be working with a quality tool that is designed and manufactured to produce a perfect part to the customer specification.  When working with a quality tool, and the specified material, an experienced molder will produce precision parts to specification.   

In addition to the molding parameters such as the size of press, and the material used, the mold design has vital impact on the quality of the parts produced in the manufacturing process.  

Mold Design for Precision Parts Manufacturing

Producing precision parts consistently to customer specifications requires a flawless mold.  The mold design will be based on the part design, usually provided by the customer.  In some cases, an experienced mold designer can assist with reverse engineering for new product design.  

Experienced mold design engineers will use computer aided design (CAD) software to assist with an injection mold design, providing detailed prints that can be shared with the injection molder for collaboration on critical areas.  When necessary, mold flow analysis can show the mold maker, and the injection molder a detailed computer simulation of how the material will melt, flow and fill.

Precision parts molders need a precision mold maker in their vendor list, a mold maker like Michiana Global Mold that offer value added services with custom injection molds within specification, and delivered on time.  For full service mold making and tooling services from an experienced, professional and high performing mold making company, contact Michiana Global Mold.
