A process for making an object from plastic material includes the following operations: moulding at least one insert, injecting a first plastic material into a first moulding cast, such first cast being configured so that the at least one insert includes a base from which exposure reliefs extend, intended to be visible when the object made of plastic material is finished, between the exposure reliefs passage channels being defined for a second plastic material in a subsequent overmoulding operation; positioning the insert in a second moulding cast, so that the insert is positioned with the base pressed against a first surface of a first half-mould of the second cast, and with the exposure reliefs pressed against an opposite second surface of a second half-mould; overmoulding a second plastic material on a part of the insert, injecting the second plastic material into the second cast, so that the second plastic material injected fills the second cast passing through the passage channels defined between the exposure reliefs of the insert, covering the base and being interposed between the exposure reliefs.

A molded pot is provided with imperfections manufactured by manufacturing mold tooling with imperfections by obtaining a handmade pot. The handmade pot is scanned to obtain geometric data. The geometric data is converted to mold tooling geometric data. Mold tooling is manufactured from the mold tooling geometric data. The handmade pot is obtained with imperfections. The handmade pot is scanned to obtain the geometric data of the handmade pot with the imperfections. The geometric data is converted to mold tooling geometric data with the imperfections. The mold tooling is manufactured with imperfections. A pot is molded with imperfections from the mold tooling.

The device includes a mold block having at least one thermoforming chamber (28) having an inside surface (29), an axial opening (28A) through which a decorative wrap-around label (38) can be inserted into the chamber, and a moving end-wall (40) opposite from the opening. The end-wall is suitable for moving in an end segment (28A) of the chamber (28) between a positioning high level and at least one thermoforming low level, and the device has at least one tongue-and-groove set comprising a fin (42) on the end-wall (40) that is engaged in a notch (44) in the inside surface of the end segment (28B).

A process for producing a biomaterial product based on sunflower seed hulls/sunflower seed husks comprising providing or producing a sunflower plastic compound (SPC) compounded material (SPC PBS, SPC PBSA), wherein the material is obtained by compounding a sunflower seed hull material/sunflower seed husk material with a biodegradable plastic, for example polybutylene succinate (PBS), polybutylene succinate-adipate (PBSA), or the like. The SPC compounded material is preferably used for producing an injection molded product, for example biodegradable containers, packagings, films or the like, in particular coffee capsules, tea capsules, urns, cups, plant pots, flowerpots, or the like.

A plant container has a base and a sidewall upwardly extending from the base. The sidewall includes stepped sidewall sections that each include a plurality of generally vertical sidewall panels having successively larger cross-sectional dimensions with distance from the base and horizontal ledges extending between an upper edge of an adjacent lower one of the sidewall panels and a lower edge of an adjacent upper one of the sidewall panels. The sidewall further includes a plurality of ribs, where each rib is formed between two of the stepped sidewall sections and extends inwardly across the ledges of the two stepped sidewall sections. Each rib has two legs that extend apart to form an outwardly-directed open channel. Holes are formed in the sidewall for air root pruning, where each hole is formed directly between a ledge and a leg of one of the ribs.

An air root pruning container for growing a plant includes a base and a sidewall upwardly extending from the base. The sidewall includes stepped sidewall sections, each stepped sidewall section including a plurality of generally vertical sidewall panels having successively larger cross-sectional dimensions with distance from the base and horizontal ledges extending between an upper edge of an adjacent lower one of the sidewall panels and a lower edge of an adjacent upper one of the sidewall panels. The sidewall further includes a plurality of ribs, each rib formed between two of the stepped sidewall sections and extending inwardly across the ledges of the two stepped sidewall sections, wherein each rib has two legs that extend apart to form an outwardly-directed open channel. Still further, the sidewall includes holes formed in the sidewall, each hole formed directly between a ledge and a leg of one of the ribs.

A method of manufacturing a plastic product (1) having a bottom and an upright wall extending from a periphery of the bottom in an injection mold having a bottom-forming cavity and a wall-forming cavity. The cavities of the injection mold are filled with fluid plastic while pressure is being exerted in two stages with an interruption of the supply of fluid plastic therebetween.
