CUSTOM TOOLING
Injection Molds
HecosTech supplies custom plastic injection tooling, including general-purpose part molds and in-mold labeling molds. Cavity arrangement, runner, cooling and ejection are selected around the part, resin and intended molding machine.

Tooling or Finished Parts?
Choose a mold for your own production operation, or a finished-parts supply project. Tool ownership, trial samples and supporting equipment are agreed separately.

Custom Injection Tooling
In-Mold Labeling Tooling
Application Review
Thin Wall Container Molds. Start with the container drawing or sample, resin and wall-thickness target. Review flow length, gate and cavity layout, cooling and product release together with the available machine details. Where in-mold labeling is required, include label positioning, removal and stacking needs in the tooling discussion.
Bottle Cap Molds. Provide the cap drawing or sample and matching bottle-neck finish, together with resin and closure requirements. Review the thread profile, sealing structure and any tamper-evident features. Define the fit, opening and sealing checks around the actual bottle, filling process and closure specification before agreeing the tooling scope.
Plastic Bucket Molds. Send the bucket drawing or sample, capacity, dimensions and resin, plus lid-fit and handle requirements. Include label dimensions, product removal and stacking needs where relevant. Review these details alongside the intended machine information so the bucket geometry, tooling and handling interfaces can be considered together.
PET Preform Mold Selection
Choose the tooling scope before comparing proposals. A PET preform mold makes the preform for subsequent bottle forming. Bottle-body tooling and bottle cap molds have separate design requirements. Provide the bottle and preform drawings together so the neck finish and downstream process can be reviewed in context.
| Selection question | PET project basis |
|---|---|
| Which preform configuration? | Identify the preform and neck-finish drawing revision, target preform weight, PET resin and intended bottle application. Discuss cavity and runner choices against the production requirement. |
| Which machine and handling arrangement? | Provide the available machine dimensions and capability information. Where takeout is included, use the preform transfer review to identify the actual handled group, access path and receiving scope; cavity count alone does not define that task. |
| Which samples support the comparison? | Use the PET trial evidence record to connect sample origin and cavity references with separate weight, dimensional and visible-defect results. Keep untested conditions and unresolved differences visible. |
Compare cavity count against demand, review runner choice against the tooling arrangement, and use the trial-sample approval guide to record release scope. These discussions help define the proposal; they do not establish a tested result.
Request a mold engineering review with the drawing revisions, proposed configuration, available sample evidence and open scope items.
Crate and Pallet Mold Selection
For reusable transport packaging, first identify whether the project is a crate or a pallet. Use the actual product drawing or sample to choose the tooling discussion below.
| Tooling family | Information that distinguishes the project |
|---|---|
| Plastic crate molds | Define the crate dimensions and resin, with ribbed or open-grid, nesting or folding features where applicable. Include stacking, cleaning and repeated-handling requirements so these can be reviewed with the product structure. |
| Plastic pallet molds | Define the pallet deck and forklift-entry arrangement, resin and intended use. State the applicable static, dynamic or racking load requirements, and review product extraction and placement with the proposed machine and end-of-arm tooling. |
The linked product pages carry the family-specific design and machine requirements. For pallet projects, identify the engineering review and physical-test evidence needed for the actual design; choosing a mold family does not approve a load rating or equipment fit.
Compare cavity count and runner choice against the selected product and production requirement. Use the trial-sample approval guide to keep the sample evidence and release scope connected to that project basis.
Send the selected product drawing or sample references, resin, intended machine, load or handling requirements and open decisions for a transport-packaging mold engineering review.
Tooling Options & Machine Fit
Part Reference
Part geometry, mating features and the approved revision establish the design basis. Open design choices are resolved before the tool arrangement is fixed.
Resin and Surfaces
Resin, visible surfaces and permitted gate locations guide tool material, texture and finish. Gate and ejection marks are assessed against the agreed appearance reference.
Production Requirement
Single- or multi-cavity tooling and hot- or cold-runner arrangements are evaluated against demand, part release and the intended molding process. Output and mold-life targets require project confirmation.
Machine Interface
Platen and tie-bar dimensions, mold thickness, opening, ejection and nozzle information determine machine fit. Selection uses the intended machine configuration.
Handling and Connections
Product takeout, labels and downstream equipment affect access and connections where relevant. Existing equipment is distinguished from items included in the proposal.
Acceptance and Supply
The supply scope identifies the tool, trial samples, agreed checks and supporting documents. Parts production and automation remain separate unless expressly included.
Agree What Each Review Must Establish
Design Basis
Trial Sample Review
Approval and Handover
Mold supply, ongoing parts production and automation are separate quotation items unless expressly included. Confirm any trial, inspection, spare-part or documentation requirement for your project.
Injection Mold Questions
Review the tooling, machine interfaces and approval basis together. Keep open requirements visible when comparing proposals.
Can I start without a complete drawing?
Yes. Share the available drawing, physical sample or concept and identify what is undecided. Material, functional features, dimensions and machine information still need to be established before the tooling scope is confirmed.
Must I choose the cavity count and runner first?
No. Provide the part, material, production requirement and available machine information. A preferred cavity count or runner type can be reviewed with the complete tooling and handling arrangement rather than treated as a fixed starting specification.
Does the mold quotation include plastic parts or automation?
Only when those items are explicitly included. State whether you need a mold, ongoing molded-part supply or a wider production arrangement. Keep tooling ownership, supplied equipment and customer responsibilities clear in the proposal.
Does the first trial sample mean the mold is approved?
Not by itself. Review the sample against agreed dimensions, appearance and functional requirements. Record open findings and the evidence needed, then define exactly which tool revision and project stage the approval covers.
