10-Plastics Mouldings-Tolerances – Moldes

Dimensions in table 2 not related to the mould are dimensions determined by the interaction of movable elements of the mould, e.g. wall thickness dimensions and bottom by the shims or mould slides. Note: the tolerances on these dimensions are greater than those on the mould-related dimensions because the movable parts of the mould do not always reach the same final position when the mould is .

DIN 16742: Plastic Moulded part tolerances for position tolerances - Knowledge - Deep Mould Co.,Ltd

The deviations from the nominal dimensions and the subsequent processing of our parts are generally dependent on the manufacturing or production processes used. DIN ISO 16742 applies for injection moulding, and the tolerance group TG 6 applies for our thermoplastics. DIN 12020-2 applies for the production of aluminium profiles.

Tolcap: Tolerance capability data for product design - Tolerancing - Tolcap or DIN 16901?

The capable tolerance for a dimension of 100mm is ± 0.186mm, which is close to the ± 0.2mm we found from DIN 16901 row 110B above. Indeed the map is a good fit to the 110 B Tolerance Group: Comparison of Tolcap plastic mould, Cpk = 1.33, tolerance suggestions with tolerances from DIN 16901. - it should be - the standard did inform our .

How to Determine Realistic Tolerances for Plastic Injection Molded Parts

Start with dimension no. 1 (2.0±0.1). In order to achieve this dimension on the product, we add shrinkage for mold production. Assume that the shrinkage rate is 2%. Cavity dimension will be 2.0/0.98=2.0408 mm, meaning: in order to meet the nominal dimension (2.0) the cavity dimension will be 2.0408mm.

Injection Moulding Design Tips - Draft, Thickness, Tolerances.

Thick features. Here's a nice & simple rule: the 2/3 rule. If you need a boss or rib on an injection moulded product, the width of the boss shouldn't be more than 2/3 of the thickness of underlying wall. Otherwise, you'll get sinking of the plastic material underneath the feature. A way to get around this problem is to core out thick areas.

Dimensional Tolerancing

Register is usually controlled by dowel pins and bushings or by self-registering cavities. There are four levels of dimensional tolerances that are used for molded products. "A1" High Precision. "A2" Precision. "A3" Commercial. "A4" Basic. The level selected should be based upon the need with the following guidelines.

ISO 20457:2018(en), Plastics moulded parts ? Tolerances and acceptance conditions

The tolerance standards applicable for metal parts, therefore, cannot be adopted for plastic structures or can only be applied to a very limited extent which led to the development of this document. The unique properties of plastics mean that three different dimensional reference levels defined in Annex A and characterized in respect to the main influential factors are taken into consideration.

Injection molding: The manufacturing & design guide

Injection molding is widely used today for both consumer products and engineering applications. Almost every plastic item around you was manufactured using injection molding. This is because the technology can produce identical parts at very high volumes (typically, 1,000 to 100,000+ units) at a very low cost per part (typically, at $1-5 per unit).

The major factor is different wall thickness as a thick section normally shrinks more than a thinner section. Mold design, gate position and process control can minimize this effect, however, the basic material behavior cannot be corrected 100%. Therefore a practical tolerance must be negotiated with the respective production units.
