RAJNA-i0123 compound for injection-moulded cutlery
A compound positioned for the manufacture of injection-moulded cutlery and similar thin-walled products, described in the current product list as containing a “green” release-agent system.
Product positioning of RAJNA-i0123
RAJNA-i0123 is the grade within the Friend Plastic RAJNA compound range intended for the manufacture of cutlery. The current public product list describes it as a biodegradable compound for cutlery containing a “green” release agent.
Documentation limitation: the public product list does not currently state verifiable processing temperatures, moisture limits, mechanical data or a specific food-contact declaration for this grade. These must be confirmed from the current TDS, SDS and compliance documentation before publication or serial production.
Typical products and manufacturing objectives
Cutlery products are commonly thin-walled injection-moulded parts with long flow paths and locally complex geometry. Material, mould design and processing conditions therefore need to be optimised together for reliable filling, ejection and cycle stability.
Spoons and stirrers
Thin-walled products with long flow paths, where complete filling, stiffness and distortion-free ejection must be achieved together.
Forks and knives
Ribbed, toothed or locally variable wall-thickness geometries requiring finished-product mechanical validation.
Custom food-service items
Dispensing tools, sample products or custom catering components developed for clearly documented conditions of use.
The role of the release-agent system
An internal release agent is generally intended to support part ejection and reduce adhesion to the mould. Actual performance, however, also depends on mould surface, draft angles, ejector design, cooling and part geometry.
What should be checked during a production trial?
- Ejection force and permanent deformation of the part.
- Adhesion on cores, ribs and textured surfaces.
- Surface appearance, staining and deposits.
- Mould venting and cleaning frequency.
- Cycle-time stability and reject rate.
- Printability, coating or bonding where relevant.
Processing and mould-design considerations
The exact processing window must be established from the current technical data sheet and production trials. The following items are key review points when preparing a cutlery injection-moulding project.
| Material preparation | Drying temperature, drying time and target moisture content must be taken from the current RAJNA-i0123 technical data sheet. |
|---|---|
| Runner and gate system | Long flow paths and thin walls require suitable gate sizing, balanced distribution and, where necessary, multiple injection points. |
| Mould venting | Adequate venting is required near fork teeth, knife edges, ribs and end-of-fill regions to reduce short shots and burn marks. |
| Ejection system | Ejector area and distribution should prevent bending, cracking or permanent deformation of the thin-walled product. |
| Cooling and cycle time | Uniform mould temperature and cooling are important for controlling warpage, shrinkage and cycle repeatability. |
| Release performance | The effect of the internal release system must be validated on the actual mould surface, geometry and representative cycle count. |
| Reprocessed material | Any permitted regrind ratio and its effect on mechanical and compliance performance must be defined through documented trials. |
Food-contact use
Because cutlery is intended to contact food, the full compliance chain must be documented. The RAJNA-i0123 product name alone does not establish compliance of the finished article.
Raw-material documentation
Request the current declaration of compliance and verify the food-contact status of the complete formulation, including the release-agent system.
Production traceability
Record material batch, drying and moulding parameters, colourant and every additional additive used in production.
Finished-product testing
Migration and functional testing must reflect the actual food or simulant, contact time, temperature and intended use conditions.
Compliance notice: before publication, verify which current documents support food-contact, bio-based content, biodegradability or compostability statements for RAJNA-i0123. Environmental or compliance claims should only be made with a defined standard, test method and applicable product conditions.
Recommended production-trial and testing programme
Mould trial
Evaluate filling, trapped air, weld lines, surface quality and ejection under several controlled processing conditions.
Mechanical testing
Bending, fracture, tooth or edge loading and representative finished-product functional tests.
Heat and moisture exposure
Dimensional, deformation and functional testing at the intended service temperature and contact duration.
Compliance testing
Migration, sensory and documentation checks defined for the target market and actual use conditions.
Frequently asked questions about RAJNA-i0123
Which products is RAJNA-i0123 intended for?
The current Friend Plastic product list identifies it as a compound developed for the manufacture of cutlery.
What does “green release agent” mean?
It is the manufacturer wording used in the product name. Its precise composition, origin and compliance status must be interpreted from the current TDS, SDS and supplier declaration.
Does the release system guarantee trouble-free ejection?
No. Ejection also depends on mould surface, draft angles, ejector design, cooling and part geometry.
Can the material be used for food-contact articles?
Only where current raw-material documentation supports the intended use and the finished article is assessed under its actual conditions of use.
Is the finished cutlery biodegradable or compostable?
Such a claim requires a specified standard, test result, product thickness and disposal environment. The material name alone does not demonstrate compostability of the finished article.
Do you need RAJNA-i0123 documentation or trial material?
Send Tibor Sipos the cutlery drawing, wall thickness, mould concept, intended service temperature, food-contact conditions and estimated annual volume. Based on this information, Friend Plastic can assess suitability and define the required production-trial programme.
