What is production tooling?

Production tooling refers to plastic injection molding molds that can withstand mass production while maintaining tight dimensional tolerances on each finished part.

Wintech selects the best qualified raw materials, advanced MoldFlow software, precision mold design and precision machining combine to create production tools that can be cycled millions of times without degradation.

The Plastic Injection Molding Process

Once your plastic injection mold tools are ready, the molding process consists of the following basic steps:

Step 1. The plastic resin comes in raw pellets. These are dried to the right moisture content, and then if necessary they can be blended with pigments or master batch colorants.

Step 2. The dried pellets are poured into the hopper of the molding machine. A reciprocating screw inside the barrel of the machine will transport these pellets towards the mold.

Step 3. Within the barrel, the pellets are mixed and heated until fully molten, forming the liquid resin.

Step 4. The heated mold closes automatically and resin, under great pressure, is injected through a gate and into the mold cavity.

Step 5. The mold is cooled to solidify the part inside.

Step 6. The mold opens and the part is ejected to begin a new cycle.

Molding Tolerances

Molding tolerance is a specified allowance on the deviation in parameters such as dimensions, weights, shapes, or angles, etc. To maximise control in setting tolerances there is usually a minimum and maximum limit on thickness, based on the process used. Injection molding typically is capable of tolerances equivalent to an IT Grade of about 9–14. The possible tolerance of a thermoplastic or a thermoset is ±0.008 to ±0.002 inches. In specialised applications tolerances as low as ±5 µm on both diameters and linear features are achieved in mass production. Surface finishes of 0.0500 to 0.1000 µm or better can be obtained. Rough or pebbled surfaces are also possible.

All plastic material will expand and contract under the influence of heat and moisture. Our tolerance guide will give more general information on the characteristics of most common resin types for typical part features.

We will work closely with you to optimize your designs for manufacturing. We will indicate any areas where poor design may produce thermal stress, shrinkage, warping, etc. Consult our design guide for more information on common defects and how to avoid them.

Design For Manufacturing

Our Design for Manufacturing review identified areas of the CAD model that could cause molding defects, so that’s always our first priority to address. We also find that at this level of detail we can offer the customer opportunities to make minor improvements that they may have overlooked, so now is a great time to implement them.

We worked with the customer to understand critical tolerances or other dimensions that could not be modified and then worked within those constraints. We then prepared a powerpoint file to share with the client, highlighting the most important areas for their feedback.
