Chair molding solution
1. plastic material: normally use PP material(shrinkage 1.6%), sometimes add CACO3 to get better smooth product appearance

2. runner system: edge gate, or hot runner directly gate

3. demoulding system: injection pin on the rib of chair bottom
if with robot help demoulding, then need to push up
if automatic demoulding, then need to overturn push down

4. back insert inchangeable
suggest not to choose transversal striations, because easy to cause jointing line

5. chair mould injection machine
chair gram weight less than 2500, 650T injection machine is enough
little larger chair, need 780T
chair with arm, or rear leg with U groove or triangle groove, then need 1080T

6. Chair molding ycle time

If you have any new project of chair mould, feel free to send me enquiry.

Pallet mold technology

Turnkey pallet molding invest cost normally is big, because of its large size also injection molding machine needed very large tonnage. Then what should be paid attention to during pallet molding to have the best quality mould and injection molding machine, then to have the max. return on investment?

Pallet mould system:
* Standard pallets,
* such as 1200*1200mm, 1200*1000mm,
* 1000*1000mm, 1000*800mm
* Non-standard pallet moulds
* 4 slide system
* Clip type pallet
* Simple type system pallet and
* pallet components mould

need to know static load and moving load that you required before the quotation
also need gram weight, detail dimension and detail pallet picture or designs


Hot runner system: 12 tip or 16 tip hot runner, filter system for recycle material application

Steel application: normally P20 steel used, but if required output is very high,
then suggest H13 steel, guaranteed 500K shots mould life time

Interchangeable system for different version


Required pallet mould injection molding machine,
for example single-deck will need 1800T, and if double-deck pallet, need 2500T.
Detail should according to your pallet product.
suggest servo motor injection machine, can saving 50-60% energy using for long term running.


For further technical details, kindly directly contact with me.

Bi injection and over molding

A, double color injection mold

the only injection machine injects two kinds of plastic material. The product forms by 2 times but depanning once. Generally this molding craft is called double material injection, which is finished by only one mold. But it must be implemented in the special double color injection machine.


B, over molding

two kinds of plastic material may not injected by only one machine, and the product forms by 2 times. It will be injected in the other mold after being removed from first mold for the first injection. So generally this type of injection craft is finished in two sets of molds but doesn’t need special injection machine.

Overview: 

Designing over molding, we should pay attention to the fixed position of hard plastic pieces. There must be anti rank hole on the piece which can prevent frictional pullar from deformation.

Double color injection mold becomes more and more popular. Because the outlook of products can be more nice by this craft. and it is easy to change colors, without spraying as well. However the cost of manufacture is high and technical requirements are needed more.

1, cavity has 2 different shapes that form different products separately. 2 shapes on the core are totally same. 

2, front and back mold must be coincided after both of them rotate 180 degree. This checking action must be designed in advance.

3, we should pay attention to the position of ejector pin hole, of which min distance is 210mm. the number of ejector pin holes should be increased in bigger mold. Because ejector pin of injection machine is not long enough, we must length it when we are designing the mold. Ejector pin can reach 150mm higher than mold base plate. Back mold base plate is made with 2 locating rings.

4, the total thickness of front mold panel and plate a is not less than 170mm. please check this specification and other reference data of machine, such as max and min mold containing thickness, distance of ejector pin hole etc.

5, the gate of three plate mold had better demold automatically. Especially for the soft plastic material.

6, the depth of former sprue can’t be over 65mm. the distance from the top of upside sprue (side gate) to the centre of mold base is not less 150mm.

7, when designing the second shape, we can design a part of clearance on the cavity for fear of scratching sprue position of first formed product. We also consider the intensity of sealing carefully.

8, when first injecting, product dimensions can be molded little bigger which can let the product press to the other cavity more closely, for sealing of second injection.

9, when second injecting, we must be sure whether the plastic flow will rush out the first forming product, if it is possible; we must try to find way.

10, before a and b plate closing, please pay attention to slider and lifter of front mold which returns to crush the product. Thus, slider and lifter should return after a and b closing.

11, waterway of 2 parts on both cavity and core must be arranged fully and evenly.

12, because soft plastic reformat easily, mostly we inject hard plastic part on product firstly and then soft plastic part.

Bi-Injection Applications

Bi-injection technological from 1970 years to become the industrialization the method since. Until recently have been extensively applied, but this is not because of its own unadaptable caused; Instead, Bi-injection adaptability is very good. And have many advantages, can improve the product quality and productivity,Application cannot extensively applied, is due to special structure to demand double colors injection molding equipment, all the double colors injection all need of two or more than two sets of reciprocating screw injection molding device, their respective plasticizing and injection of different materials, and should have coordinate their action steps automatic control equipment, And at that time environmental condition equipment utilization rate is not high.

But now, as people of plastic products quality requirements, and improve injection machinery industry and automatic control technology level of development, bi-injection technological used more widely and more attention by people. the application scope such as Daily necessities,Automotive, Mobile digital products and so on...
